Managing Insomnia on GLP-1: A PillSorted Guide

If you’re on a weight loss journey using GLP-1 medications like Mounjaro or Wegovy, you might find yourself struggling with sleep. Experiencing insomnia on GLP-1 is not uncommon, and it can be frustrating when you’re trying to improve your overall health. Pharmacist Zeinab Ardeshir from PillSorted explains why this might happen and what you can do to get a better night’s rest.

Why Might Sleep Worsen on GLP-1?

When you embark on a weight loss journey, particularly with medications like GLP-1s, your body undergoes significant changes. This can sometimes lead to disruptions in your sleep patterns. Pharmacist Zeinab highlights two common reasons why you might experience worsened sleep or insomnia on GLP-1:

• Hunger at the end of the day: GLP-1 medications help you feel fuller for longer, leading to a calorie deficit throughout the day. While this is beneficial for weight loss, going to bed feeling genuinely hungry can make it difficult for your brain and body to relax and switch off. Your body might be sending signals of needing nourishment, keeping you alert.
• Heavy meals close to bedtime: Conversely, if you haven’t managed your calorie intake well during the day and find yourself eating a large, heavy meal just before bed, your body will be working hard to digest it. This active digestion can increase your core body temperature and make it challenging to enter the deep, restorative sleep stages.

Both scenarios can contribute to a restless night, exacerbating any existing sleep issues or creating new ones while you’re focused on improving your obesity or diabetes management.

Lifestyle Adjustments for Better Sleep

Addressing sleep difficulties often starts with simple, consistent lifestyle changes. These adjustments can significantly improve your chances of overcoming insomnia on GLP-1 and achieving better rest:

• Keep a consistent routine: Our bodies thrive on routine. Melatonin, a crucial hormone for sleep, naturally increases around bedtime and decreases in the morning. By going to bed and waking up at roughly the same time each day, even on weekends, you help regulate your body’s natural circadian rhythm, making it easier to fall asleep and wake up feeling refreshed. This consistency is a cornerstone of healthy living.
• Create an unwinding time: Dedicate the hour or two before bed to relaxing activities. This “unwinding time” signals to your body that it’s time to prepare for sleep. Ensure your bedroom is quiet, dark, and cool. A slightly cooler room temperature (around 18°C) is often ideal for sleep.
• Avoid stimulating activities: In the hours leading up to bedtime, avoid anything that might stimulate your brain or body. This includes strenuous exercise, engaging video games, or even too much screen time from phones, tablets, and computers, which emit blue light that can interfere with melatonin production. Opt for calmer activities like reading a book, listening to soothing music, or taking a warm bath.

Implementing these practices can create a conducive environment for sleep, supporting your overall general health and well-being.

Dietary Strategies to Combat Insomnia on GLP-1

What and when you eat can have a profound impact on your sleep quality, especially when managing your diet on GLP-1 medications. Here are some food-wise tips to help manage insomnia on GLP-1:

• Don’t go to bed too hungry: If you’re feeling hungry before bed, a light, balanced snack can help. Choose something small that won’t overload your digestive system, such as a piece of fruit, a handful of nuts, or a small pot of yoghurt.
• Opt for calming drinks: Herbal teas, particularly chamomile tea, are well-known for their calming properties and can help you relax before sleep.
• Consider milky desserts: If you don’t have a dairy allergy, a small, warm milky dessert can be comforting and may aid sleep. Milk contains tryptophan, an amino acid that helps produce serotonin and melatonin, which are crucial for sleep.
• Avoid triggers: Certain substances and foods can act as stimulants or disrupt digestion, making sleep difficult.
  • Smoking: Nicotine is a stimulant and can interfere with sleep.
  • Alcohol: While it might initially make you feel drowsy, alcohol disrupts the natural sleep cycle, leading to fragmented sleep later in the night.
  • Heavy, spicy foods: These can cause indigestion and heartburn, making it uncomfortable to lie down and fall asleep. Try to consume your main meals earlier in the evening.

Natural Supplements to Consider

Certain supplements can be helpful in supporting natural sleep processes, especially when dealing with occasional insomnia on GLP-1. Magnesium and Zinc are two key minerals that play a role in sleep regulation:

• Magnesium: This essential mineral helps regulate melatonin, the sleep-inducing hormone. It also helps relax muscles and calm the nervous system, contributing to a more restful state.
• Zinc: Zinc is involved in numerous bodily functions, including the production of melatonin. Ensuring adequate zinc levels can support your body’s natural sleep-wake cycle.

PillSorted offers pharmacist-designed supplements that include these beneficial minerals, tailored to support your overall health and well-being during your weight loss journey.

Over-the-Counter Sleep Aids for Short-Term Insomnia on GLP-1

For temporary periods of sleep disruption, certain over-the-counter (OTC) options can help you get back into a routine. It’s important to remember these are generally for short-term use only (typically no more than one to two weeks).

• Herbal Tablets: Products like Nytol Herbal Tablets often contain extracts of hop strobil, valerian, and passion flower, which are traditionally used to aid relaxation and sleep. These can be a gentle option to help you settle down at night.
• Antihistamine Tablets: Some OTC sleep aids, such as Nytol Original (containing diphenhydramine) or Phenergan (promethazine), are antihistamines that cause drowsiness as a side effect. They can be effective for short-term insomnia on GLP-1, helping to break the cycle of sleeplessness and re-establish a healthy sleep pattern. However, due to potential side effects like next-day drowsiness and the risk of dependence, they are not suitable for long-term use.

Always read the label carefully and consult with a pharmacist before starting any new medication or supplement, especially if you are already taking other medications.

When to Seek Professional Help for Insomnia on GLP-1

While lifestyle changes and OTC remedies can be effective for many, there are times when it’s crucial to seek advice from a healthcare professional. You should consider talking to your GP or a pharmacist if:

• You’ve been having trouble falling or staying asleep for more than a couple of weeks, despite trying self-help measures.
• You wake up in the morning feeling really tired, your mouth is dry, or you feel very sleepy throughout the day, impacting your daily functioning and mental health.
• You suspect there might be an underlying health problem contributing to your sleep difficulties.

A healthcare professional can help identify the root cause of your insomnia on GLP-1, whether it’s related to your medication, an underlying condition, or other factors. They can also discuss stronger, prescription-only medications if appropriate, or refer you to a sleep specialist for further investigation. Finding out what’s causing the problem is the first step towards finding the right, personalised solution for you.
