You’ve likely heard about the new wave of “weight loss jabs” (like Ozempic, Wegovy, or Mounjaro) in the news or on social media. These medications, known medically as GLP-1 receptor agonists, are revolutionising how we treat diabetes and obesity. While they offer fantastic benefits for weight loss and heart health, it is important to be aware of how they might affect your eyes.

Here is a guide to the possible risks and what warning signs to look out for.

How Do Weight Loss Injections Work?

These medications mimic a natural hormone in your gut. They help lower blood sugar levels, slow down how fast your stomach empties (keeping you fuller for longer), and signal your brain that you have had enough to eat .

Potential Effects on Your Eyes

While serious complications are rare, there are some side effects you should know about before or while taking these treatments.

1. Blurred Vision

It is quite common to experience some blurry vision when you first start these medications.

Why does it happen? Rapid changes in your blood sugar levels can actually change the shape of the lens inside your eye .
What should I do? Don’t panic. This is usually temporary. If you are older, it might take a bit longer (up to a few months) for your vision to stabilise . It is often best to wait until your vision settles before spending money on new glasses.

2. Changes to Diabetic Eye Disease (Retinopathy)

If you have diabetes, you might already be having your eyes screened for “diabetic retinopathy” (damage to the blood vessels in the back of the eye).

The Risk: Surprisingly, improving your blood sugar levels too quickly can sometimes cause a temporary worsening of this condition. This is known as “early worsening” .
The Advice: If you have a history of eye problems from diabetes, your doctor will want to monitor you closely when you start these injections.

3. Rare but Serious Conditions

Recent studies have highlighted some less common but more serious risks:

NAION (Eye Stroke): There is emerging evidence of a potential link between these drugs and a condition called NAION, which blocks blood flow to the optic nerve and can cause sudden, painless vision loss .
Retinal Issues: Large studies have suggested a slightly increased risk of vitreous haemorrhage (bleeding in the jelly of the eye) or retinal detachment .

General Side Effects of Weight Loss Injections

Aside from your eyes, these medications are well-known for affecting your digestion. Because they slow down your stomach, they can sometimes cause nausea or more severe issues like “gastroparesis” (where the stomach becomes paralysed).

When Should You See an Optician?

You should contact your optician or eye doctor immediately if you experience any of the following “Warning Signs” :

Sudden loss of vision
New floaters (spots or cobwebs in your vision)
Flashing lights
A curtain or shadow coming across your vision
Severe eye pain
Double vision

The Takeaway

Weight loss injections can be life-changing for many people, improving overall health and reducing the risk of heart attacks and strokes. However, like all medications, they come with risks.

If you are considering these injections, or are already taking them:

Tell your Optician: Make sure they know you are on this medication.
Get Checked: It is recommended to have a comprehensive eye exam within three months of starting treatment.
Stay Alert: Keep an eye out for any changes in your vision and seek help if you are worried.

As the darker, colder months descend upon the UK, the motivation to stay active can often feel like it’s hibernating. The temptation to swap your running shoes for a duvet and embrace the sofa is powerful!

However, maintaining your fitness routine through winter is crucial—not just for your physical health, but for giving your mental wellbeing a much-needed boost against the ‘winter blues.’ The good news? You don’t have to train for a marathon; just keep moving.

Here are five effective ways to keep your body active and your spirits high during the chillier season.

1. Embrace the Outdoors (The Cold is Your Friend!)

While it seems counter-intuitive, exercising outdoors in cold weather actually offers unique benefits: your body works slightly harder to regulate its temperature, which can potentially increase your calorie burn! Plus, exposure to daylight—even on an overcast day—is vital for Vitamin D production and regulating your sleep cycles.

Tips for Outdoor Winter Workouts:

Layer Up (The Three-Layer Rule): Start with a moisture-wicking base layer (polyester/nylon) to draw sweat away, add an insulating middle layer (fleece/jumper), and top with a waterproof/windproof outer layer. You can peel layers off as you warm up.
Stay Visible: With limited daylight, wear bright colours and reflective gear to ensure you are easily seen by traffic and other pedestrians.
Watch Your Step: Be mindful of ice or frost. Opt for shoes with good grip and stick to well-lit or gritted paths.

2. Schedule Time with a Friend (The Accountability Buddy)

One of the biggest hurdles in winter is simply getting out the door. Having a friend, partner, or family member relying on you is a fantastic motivator.

Whether you join a group running club, book a spin class together, or simply commit to a brisk daily walk with a friend, that shared commitment helps ensure neither of you hits the snooze button. Studies show you are significantly more likely to stick to a routine if you have someone holding you accountable.

3. Discover the Power of Indoor Group Classes

If the thought of exercising in the rain is a genuine barrier, bring your workout inside. Leisure centres and local halls offer a massive variety of classes that can add fun and structure to your routine:

For Strength: Try a body pump, Pilates, or circuit training session.
For Cardio: Get your heart racing with Zumba, spin, or Body Combat.
For Mind & Body: Yoga is excellent for improving flexibility, balance, and mental focus during the stressful festive period.

These provide a bright, warm environment and a sense of community that can be sorely lacking during the isolated winter months.

4. Utilise Free Home Workouts (10-Minute Movement)

For those dark evenings when you just can’t face leaving the house, the internet is packed with free home workouts. You don’t need fancy equipment, just your own body weight and a floor space.

Try incorporating short bursts of activity into your day:

Swap sitting down to watch the news for a 10-minute NHS home workout video.
Walk on the spot during TV advert breaks.
Do a set of squats or star jumps every time you boil the kettle.

The key is consistency—a little bit of movement often is far better than nothing at all.

5. Don’t Forget Hydration and Warm-Ups

You may not feel as thirsty as you do in summer, but your body is still losing fluids through sweat and breathing. Dehydration can lead to fatigue, so keep sipping water throughout the day.

Finally, always dedicate at least 5-10 minutes to a warm-up before you start exercising. Cold muscles are stiffer muscles, making them more vulnerable to injury. A dynamic warm-up (like jogging on the spot or arm circles) will increase blood flow and prepare your body for the activity ahead, making the cold shock less intense when you step outside.

Decongestant Sprays (e.g., Otrivine, Sudafed): These contain active ingredients like xylometazoline or oxymetazoline. They are designed to provide fast relief by shrinking the swollen blood vessels in the nose that cause congestion. They are best used when you are severely blocked. But must only be used for a short period, otherwise there are serious complications.

As the temperatures drop and the festive season approaches, so too does the inevitable stream of winter bugs, colds, and flu. For many in the UK, the blocked nose is a defining, and miserable, symptom of a winter infection.

While a pharmacist can offer a variety of options—from paracetamol to ease aches, to lozenges for a sore throat—the nasal spray is often the first thing we reach for when we need to breathe again. But with so many types available, and warnings about overuse, should they be a staple of your winter healthcare kit? And what exactly are the risks?

1. Should I Use a Nasal Spray During Winter?

The answer is generally yes, but it depends entirely on the type of spray and what you’re using it for.

Winter air can often be cold and dry, leading to irritated nasal passages. Furthermore, respiratory tract infections (like the common cold) spike in the colder months, causing inflammation and congestion. Nasal sprays can be highly effective for managing these symptoms.

A recent University of Southampton-led trial even suggested that using certain over-the-counter gel and saline sprays at the first sign of a cough, cold, or flu could potentially reduce the severity and duration of the illness by around 20%, offering a potential way to tackle the UK’s regular winter infection surge.

The two main types of sprays for winter use are:

Saline Sprays (Salt Water): These are drug-free and contain sterile salt water. They work by moistening dry nasal passages, which is particularly useful in heated winter environments, and help to thin and flush out built-up mucus. They are safe for daily, long-term use.
Decongestant Sprays (e.g., Otrivine, Sudafed): These contain active ingredients like xylometazoline or oxymetazoline. They are designed to provide fast relief by shrinking the swollen blood vessels in the nose that cause congestion. They are best used when you are severely blocked.

2. The Benefits: Clearing Up Your Winter Woes

When used correctly, nasal sprays offer several significant benefits during the winter months:

Rapid Relief from Congestion: Decongestant sprays provide an immediate, welcome effect, allowing you to breathe clearly through your nose, which can improve sleep and general comfort.
Cleansing Action: Saline sprays are excellent for clearing out mucus, debris, and potential irritants or viruses, helping to keep your nasal passages healthy and clean.
Targeted Prevention: Some ‘barrier’ type sprays (often used at the very start of a cold) may physically trap and deactivate cold viruses in the nose, helping to stop a full-blown infection from developing.
Synergy with Other Medications: If your nose is so blocked that an allergy or steroid spray (often used for persistent rhinitis) cannot get through, a short course of a decongestant spray can clear the path, making other treatments more effective.

3. The Risks: The One Essential UK Warning

While hugely beneficial for short-term relief, there is one major risk associated with nasal sprays that the NHS and UK medical experts consistently warn against: rebound congestion.

The Danger of Decongestant Overuse (Rhinitis Medicamentosa)

Decongestant nasal sprays are highly effective, but they are not designed for long-term use.

The crucial advice from UK health bodies is simple: do not use decongestant sprays for more than 5 to 7 days.

If you continue to use a decongestant spray for longer than this period, the blood vessels in your nose can stop responding normally to the medication. As the drug wears off, the nasal tissue can swell even more than it did initially, creating a cycle where you become dependent on the spray just to breathe normally. This condition is clinically referred to as rhinitis medicamentosa.

In severe cases, long-term overuse can lead to permanent damage and thickening of the nasal structures, potentially requiring further medical intervention.

Other Potential Risks:

Common Side Effects: Some users, particularly with steroid-based sprays, may experience a dry or sore nose, nosebleeds, an unpleasant taste/smell, or headaches. If these are persistent, you should stop use and speak to a pharmacist.
Underlying Health Conditions: The NHS advises that if you have conditions like high blood pressure, diabetes, an overactive thyroid gland, or heart problems, you should speak to a pharmacist or GP before using decongestant tablets or sprays.

A Quick Guide to Spray Types

To stay safe this winter, remember the golden rule based on the product you choose:

Spray Type	Active Ingredient (Common)	Primary Use in Winter	Key UK Safety Advice
Decongestant	Xylometazoline, Oxymetazoline	Rapid, short-term relief from a cold/flu blocked nose.	Do NOT use for more than 5-7 days. Risk of rebound congestion.
Saline	Salt water, Sodium Chloride	Moisturising a dry nose, gently clearing mucus, daily hygiene.	Safe for daily and long-term use. Very few side effects.
Steroid	Fluticasone, Mometasone (often prescription)	Treating chronic conditions like persistent rhinitis, allergies, or nasal polyps.	Usually safe for long-term use, but follow your doctor or pharmacist’s instructions.

For any persistent congestion that lasts longer than a week, or if you find yourself relying on a decongestant spray to breathe, it is essential to consult a pharmacist or your GP for advice.

It’s a common misconception in the UK that if the sun isn’t shining brightly, there’s no need to worry about sun protection. We often think of sunscreen as something reserved for our summer holidays abroad or the one or two blistering days we get at home. However, at CHEC, we know that protecting your skin from the sun is a crucial, year-round commitment.

Sun exposure is the number one cause of skin damage and a major contributor to the risk of skin cancer, including melanoma. The real culprits are ultraviolet (UV) rays, and these rays are present every single day, no matter the weather.

The Unseen Threat: UVA and UVB Rays

The sun emits two types of UV rays that affect our skin:

UVA rays: These rays penetrate deep into the skin’s layers. They are the primary cause of premature skin ageing, leading to wrinkles, fine lines, and sunspots. They can also pass through clouds and even glass, so you’re still exposed indoors or on a cloudy day.

UVB rays: These are the rays that cause sunburn. They are the main cause of most skin cancers. While their intensity varies with the seasons, they are still a significant threat, particularly between 11 am and 3 pm, even on cooler days.

Even when it feels cold or looks grey outside, UV rays are still reaching your skin. Protecting yourself is not just about avoiding sunburn; it’s about safeguarding your long-term skin health.

Your Daily Sunscreen Checklist

Making sunscreen a part of your daily routine is the single most effective way to protect your skin. Here’s how you can get it right:

Always opt for a broad-spectrum sunscreen with a Sun Protection Factor (SPF) of at least 30. “Broad-spectrum” means it protects against both UVA and UVB rays.

Don’t be shy with your application. You need a generous amount to get the full protective benefits.

Reapply your sunscreen at least every two hours, and more frequently if you’re sweating or if it’s raining.

Remember to apply it to your face, neck, ears, and the back of your hands—areas that are almost always exposed to the elements.

When in Doubt, Get a Professional Opinion

Regularly checking your skin for new moles or changes to existing ones is vital for early detection of skin cancer. If you have any concerns about a mole or any area of your skin that looks unusual, don’t hesitate to seek expert advice. See our ABC’s of moles here

At CHEC, we offer NHS dermatology services, providing easy access to professional advice and care. Our team of specialists is dedicated to helping you look after your skin, so you can feel confident in your health, all year round.

Protecting your skin is a long-term investment. By making sunscreen a part of your daily routine, you can significantly reduce your risk of sun damage and enjoy the outdoors safely.

Have you noticed an increasing number of patients walking into your practice who are taking weight loss medications like Ozempic or Mounjaro? You’re not alone. The rise in popularity of these “weight loss jabs” has prompted questions from optometrists across the country, who are now asking: what are the ocular effects of these powerful new medications?

One optometrist recently reached out to us, voicing a concern that many of you share: ‘In practice, we are increasingly seeing patients who are taking the newer weight loss medications, Ozempic and Mounjaro, for example. Could CHEC inform us in more detail the ocular effects of these medications?’ At CHEC, we’re proud to partner with optometrists and we’re always here to help with any queries you may have. This is exactly why we’re hosting our national webinar, to provide the answers and support you need to navigate these new challenges.

Your patients are losing weight and managing their blood sugar, but at what potential cost to their vision? From fluctuating vision and blurred eyesight to more serious complications, the link between these drugs and eye health is an emerging and vital topic for every optometrist. The question isn’t just what these medications do to a patient’s eyes now, but what happens six months, a year, or even after they stop taking them?

The answers aren’t always straightforward. We’ll delve into the studies and data, examining topics such as:

The potential association with other conditions, such as wet AMD and NAION (Non-Arteritic Anterior Ischemic Optic Neuropathy).	The risk of blurred vision and how it can affect patients, especially at the beginning of their treatment.
The potential for worsening diabetic retinopathy, a phenomenon known as “early worsening” that can occur with rapid improvements in blood sugar control.	The link to more serious retinal issues, including an increased incidence of vitreous haemorrhage and retinal detachments.

If you’re seeing these patients and have been searching for answers, this is the webinar for you. Join Ophthalmologist Dr Moemen Elnawawy as he explores “GLP1 RAs: The Good, The Bad and Why We Should Care”.

As the days get shorter and the air turns crisp, many of us start to notice a change in our skin. That dewy summer glow can quickly give way to dryness, flakiness, and irritation. But don’t worry, you can keep your skin feeling soft and healthy all season long.

Here are some simple, effective tips to help your skin transition smoothly into autumn.

Hydration is key

Probably the most crucial step when caring for not only your skin, but your overall health. While you might have been drinking plenty of water during the summer months, it’s just as important now. Dehydration affects your skin’s elasticity and overall health, so be sure to keep a water bottle handy.

Switch Up Your Skincare

The lightweight lotions and gels you used in summer might not be enough for the cooler weather.

Use a richer moisturiser. Look for creams with ingredients like hyaluronic acid (which draws moisture into the skin), ceramides (which help restore the skin’s barrier), or glycerine.

Avoid harsh soaps. Bar soaps and cleansers with strong foaming agents can strip your skin of its natural oils. Switch to a creamy, hydrating cleanser instead.

Don’t forget SPF. Remember, just because the sun isn’t shining bright doesn’t mean it’s strong rays aren’t strong (even on cloudy days). Continue to use a broad-spectrum sunscreen to protect your skin barrier from UV damage, which can worsen dryness.

Adjust Your Shower Routine.

Long, hot showers might feel amazing on a cold day, but they can do a lot of damage to your skin.

Pat, don’t rub. Gently pat your skin with a towel after showering, leaving it slightly damp. This helps to lock in moisture before you apply your moisturiser.

Turn down the temperature. Use lukewarm water instead of hot.

Keep it short. Limit your showers to 5-10 minutes.

Protect Your Skin from the Elements

The wind and cold air can be tough on exposed skin.

Wear a scarf and gloves. Protecting your hands and face is a simple way to prevent dryness and chapping.

Use a humidifier. Indoor heating can significantly dry out the air in your home. A humidifier adds moisture back into the air, which can make a big difference to your skin, especially while you sleep.

By making a few simple adjustments to your routine, you can ensure your skin stays supple and comfortable throughout the autumn season. If your dry skin is severe or persistent, it’s always a good idea to speak with your GP or a pharmacist. They can offer personalised advice and may recommend specific treatments.

Snoring is often a source of humour or annoyance in many households, but for some, it can be a sign of a more serious underlying health issue. While a little snoring now and then is normal, chronic and loud snoring could indicate a condition that warrants a visit to an ENT (Ear, Nose, and Throat) specialist.

The Science Behind the Snore

Snoring occurs when the flow of air through the mouth and nose is physically obstructed. When you’re asleep, the muscles in your throat and tongue relax, which can cause the soft palate and uvula to vibrate as you breathe, creating the familiar sound we call snoring. Several factors can contribute to this, including your anatomy (such as a deviated septum), lifestyle choices like alcohol consumption, or allergies.

When Is It Time to See a Specialist?

If your snoring is a nightly occurrence, loud, and disruptive to both your sleep and your partner’s, it may be time to seek professional advice. Here are some key symptoms to look out for:

Daytime Fatigue: Do you wake up feeling tired even after a full night’s sleep?
Waking Up with a Gasp or Choke: This can be a sign of sleep apnoea.
Morning Headaches: Snoring can sometimes lead to oxygen deprivation, causing headaches.
Difficulty Concentrating: Poor sleep quality can affect your cognitive function.
High Blood Pressure: There’s a known link between sleep disorders and hypertension.

These symptoms could be a red flag for obstructive sleep apnoea (OSA), a condition where breathing is repeatedly interrupted during sleep. Left untreated, OSA can increase your risk of heart disease, stroke, and diabetes.

How CHEC Can Help with Snoring

At CHEC, we understand the importance of addressing the root cause of snoring and related issues. Our expert ENT specialists are equipped to provide a comprehensive assessment to determine the best course of action.

Spring is a time of renewal and vibrancy, but it also brings unique challenges for our eyes. As we shed the winter layers and embrace the outdoors, it’s crucial to take proactive steps to protect our vision. Here’s how you can keep your eyes healthy and happy this spring:

Combat Seasonal Allergies

Spring is synonymous with blooming flowers and rising pollen counts, which can trigger allergic conjunctivitis (eye allergies). Symptoms include itchy, watery, and red eyes. To minimise discomfort:

Monitor pollen counts: Stay informed about local pollen levels and limit outdoor activities on high pollen days.

Use allergy eye drops: Over-the-counter or prescription allergy eye drops can provide relief.

Avoid rubbing your eyes: Rubbing can worsen irritation and spread allergens.

Keep windows closed: During peak pollen times, keep windows closed at home and in your car.

Wear sunglasses: Sunglasses act as a barrier against pollen and other irritants.

Protect Against Increased UV Exposure

The sun’s rays become stronger in spring, increasing your exposure to harmful ultraviolet (UV) radiation. Long-term UV exposure can contribute to cataracts and macular degeneration. Protect your eyes by:

Wearing sunglasses with 100% UV protection: Choose sunglasses that block both UVA and UVB rays.

Wearing a wide-brimmed hat: A hat provides additional shade and protection.

Staying hydrated: Dry eyes can be more susceptible to UV damage.

Address Dry Eye Symptoms

Spring winds and increased outdoor activities can exacerbate dry eye symptoms. Combat dryness by:

Using artificial tears: Lubricating eye drops can provide relief.

Staying hydrated: Drink plenty of water throughout the day.

Taking breaks from screens: Follow the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds).

Using a humidifier: A humidifier can add moisture to the air.

Be Mindful of Spring Cleaning Chemicals

Spring cleaning often involves using harsh chemicals that can irritate or damage your eyes. Take precautions by:

Wearing protective eyewear: Safety goggles can shield your eyes from splashes and fumes.

Ventilating the area: Open windows and doors to ensure proper ventilation.

Reading product labels: Follow the manufacturer’s instructions carefully.

Schedule a Comprehensive Eye Exam

Regular eye exams are essential for maintaining good eye health. Schedule an appointment with your eye care professional to:

Assess your vision: Ensure your prescription is up-to-date.

Check for eye diseases: Early detection can prevent vision loss.

Discuss any concerns: Address any questions or symptoms you may be experiencing.

Practice Good Hygiene

With warmer weather, allergies, and more outdoor activities, it is important to practice good hygiene.

Wash hands often, especially before touching your eyes. See our blog on the importance of hand hygiene.
Avoid sharing makeup or personal eye care items.

By following these tips, you can enjoy the beauty of spring while keeping your eyes healthy and protected. Remember, if you experience any persistent eye discomfort or vision changes, consult your eye care professional promptly.

Enjoy a bright and clear spring!
