Many people are seeing impressive results on Wegovy. Not just for losing weight, but improving their overall health.<\/p>\n\n\n\n

So, if you\u2019re feeling more tired since starting Wegovy, you might be concerned. Isn\u2019t a healthy lifestyle supposed to give you more <\/em>energy?<\/p>\n\n\n\n

Here, we explain whether tiredness is a side effect of Wegovy<\/a> and why you might feel tired. And give you advice on what you can do to manage it and when to get help.<\/p>\n\n\n\n

Is Feeling Tired on Wegovy Normal?<\/h2>\n\n\n\n

Yes, it can be. Fatigue is listed among the common side effects on the patient information leaflet. However, this doesn’t mean everyone will feel tired while taking Wegovy (semaglutide)<\/a>.<\/p>\n\n\n\n

Some patients will feel more tired in the first few weeks of treatment. For others, they\u2019ll feel more fatigued after their dose increases. In most cases, feeling tired isn\u2019t a sign that something is seriously wrong.<\/p>\n\n\n\n

\u201cIt\u2019s usually temporary and settles with time,\u201d explains Simple\u2019s Chief Clinical Officer Abdal Alvi<\/strong>. \u201cIf you are concerned, make sure to speak with one of our clinical team.\u201d<\/p>\n\n\n\n

\u201cIt\u2019s important to make sure you are eating enough to maintain energy levels and that treatment isn\u2019t too effective for you.\u201d<\/p>\n\n\n\t\t

What Causes Wegovy Fatigue?<\/h2>\n\n\n\n

Wegovy works by mimicking a natural hormone called glucagon-like peptide-1 (GLP-1). The GLP-1 hormone is responsible for regulating your appetite. This can change how your body uses energy, which might explain the dip in your usual energy levels.<\/p>\n\n\n\n

However, there\u2019s no single cause for tiredness on Wegovy. A few factors can play a role.<\/p>\n\n\n\n

Reduced Calorie Intake<\/h3>\n\n\n\n

Like other GLP-1 weight loss medications, Wegovy suppresses your appetite and helps you stay fuller for longer.<\/p>\n\n\n\n

This means you\u2019re likely eating less and taking in fewer calories \u2013 and calories are your body\u2019s main energy source. This dip in energy intake can make you feel more tired until your body has fully adapted to these changes.<\/p>\n\n\n\n

Blood Sugar Changes<\/h3>\n\n\n\n

Semaglutide is approved to treat type 2 diabetes as well as for weight management. That\u2019s because it can affect how your body releases insulin and processes sugar.<\/p>\n\n\n\n

If your blood sugar levels drop lower than normal, you might feel sluggish, lightheaded, or drained.<\/p>\n\n\n\n

Digestive Side Effects<\/h3>\n\n\n\n

Nausea, vomiting, and diarrhoea are common in the early weeks of treatment. They can lead to dehydration or reduced food intake. Both can contribute to tiredness.<\/p>\n\n\n\n

Dose Adjustments<\/h3>\n\n\n\n

Many people notice an increase in fatigue when they move up a dose. It should settle as your body adapts to the dose.<\/p>\n\n\n\n

This is why your healthcare provider will increase your dose gradually \u2013 it helps you to build tolerance.<\/p>\n\n\n\n

Other Health Factors<\/h3>\n\n\n\n

The tiredness you feel may not be caused by Wegovy.<\/p>\n\n\n\n

Poor sleep, high stress and other medications can also leave you feeling drained. So can underlying medical conditions such as anaemia (low iron levels) or thyroid problems, according to the NHS<\/a>.<\/p>\n\n\n\n

That\u2019s why it\u2019s important to let your healthcare provider know about any persistent fatigue. They can help identify the cause, rule out other health issues, and make sure you\u2019re getting the right treatment or support.<\/p>\n\n\n\n

Does Wegovy Fatigue Go Away?<\/h2>\n\n\n\n

For many people, yes. Fatigue often improves within a few weeks once your body adjusts to the medication and your new eating habits.<\/p>\n\n\n\n

If your tiredness is linked to dose increases, it may settle again after a short adjustment period. Some people find the tiredness goes away completely. Others notice they still tire more easily than before but can manage it with lifestyle changes.<\/p>\n\n\n\n

However, if your tiredness is severe, persistent, or getting worse, it\u2019s worth speaking to your healthcare provider. There may be another cause, or your dose or treatment plan may need adjusting.<\/p>\n\n\n\t\t
