Getting a good night’s rest is essential for weight loss and overall health. Sleeping well can help your body regulate levels of key hormones that control your appetite. It can also stop you reaching for sugary snacks when you need a quick energy boost.

If you’re taking Mounjaro or Wegovy (link) for weight loss, you may find the medication affects your sleep and makes you feel more tired. Here, we look at how you can successfully overcome these challenges, improve the quality of your sleep while injecting and increase your chances of weight loss success.

Key Takeaways

1 | Sleep disturbances may be temporary when starting Weight Loss Injections

2 | Quality sleep can support weight loss and general wellbeing

3 | Simple adjustments to sleep habits can help manage any sleep changes

How Do Weight Loss Injections Affect Your Sleep?

Insomnia and trouble sleeping aren’t listed as common Mounjaro or Wegovy side effects. However, some people taking these medications do experience sleep disturbances.

There could be a few different reasons weight loss injections impact sleep. Nausea, vomiting and diarrhoea are all common side effects of the medications, and if you experience these symptoms at night, it could affect the quality of your sleep.

Appetite changes caused by Wegovy or Mounjaro may also make it harder to sleep. The medication is designed to slow the speed that food passes through your digestive system and make you feel fuller for longer. This could impact your energy levels and your sleep patterns.

Mental health issues can also interrupt sleep, and as some people have reported mood shifts when taking these medications, it’s possible that this could also impact your sleep quality. Get in touch with a member of our team if you’d like support or information about managing anxiety on weight loss jabs.

Why Is Good Sleep Important For Weight Loss?

Sleep is a very important part of weight loss. Getting a good night’s sleep promotes the healthy production of hormones that control the appetite, helping you to feel less hungry and consume fewer calories.

If you don’t get enough sleep, it could slow your metabolism (the rate at which your body burns calories) and make it harder for you to lose weight. Studies have also shown that we’re more likely to reach for snacks that are high in sugar and carbohydrates when we're tired.

Improving the quality of your sleep could see you achieve even better results when taking Mounjaro or Wegovy. In fact, research shows that getting better quality sleep could increase your chances of weight loss success by up to 33%.

Common Sleep Challenges Weight Loss Medication

One of the most common challenges with sleep on weight loss medication is nausea. For example, around one in five people who take Mounjaro will feel some level of nausea, and up to one in 10 will experience vomiting. If you feel sick during the night, it may make it more difficult to fall asleep and get good quality rest.

Some people who take Mounjaro or Wegovy have reported that their dreams become extremely vivid. While this isn’t a symptom listed in the Mounjaro side-effects guide or our Wegovy side effects guide, these dreams could cause you to wake up more regularly and make it more difficult to get back to sleep again.

In most cases, these symptoms are temporary and manageable and should begin to ease as your body adjusts to the medication. If you feel weight loss medication is having a significant impact on your ability to sleep, talk to your doctor or another healthcare professional.

Tips For Better Sleep While Taking Any Weight Loss Medication

Understanding more about medication and sleep can make it easier to get a good night’s rest. As we’ve already seen, improving rest on Mounjaro or Wegovy could help to boost your weight loss results, so it’s important to work on your sleep routine.

One of the best ways to improve your sleep quality is through sleep hygiene. This means creating healthy habits and behaviours that will help you drift off easily and get plenty of rest. For example, you could:

  • create regular bedtime rituals
  • go to bed at the same time every night
  • avoid caffeine and other stimulants after lunch
  • remove digital devices from the bedroom
  • keep your bedroom clean and clutter-free

Increasing the amount of exercise you do, and using meditation to relax before bed, could also help you to get better, more restful sleep.

It is essential that you speak to a licensed medical professional before starting any weight loss medication. They can provide personalised, expert guidance, assess potential risks and ensure that your chosen treatment is safe and suitable for your health needs.

For most people, these sleep challenges are temporary and should ease as your body adjusts to the medication. Improving your sleep hygiene, and prioritising rest, could help you to manage these challenges and boost your chances of losing weight.
