Does Semaglutide Cause Fatigue or Tiredness?

So, you’ve started your journey with semaglutide, and you’re excited for the changes ahead. But you might have noticed something you didn’t expect: you feel really tired. If you’re asking yourself, “does semaglutide make you tired?” you are not alone.

Feeling this way is a common experience for some people. This guide will explain why you might be feeling drained and give you simple tips to get your energy back.

Yes, Feeling Tired Can Be a Side Effect — Here’s Why

First, it’s important to know that feeling tired can be a normal side effect. It doesn’t happen to everyone, but it’s definitely something people report. It’s not just in your head!

There are a few simple reasons why you might feel this way as your body gets used to the medication.

Your Body is Adjusting to Fewer Calories

Semaglutide is very good at quieting your hunger signals. This means you naturally start to eat less food and fewer calories. When your body suddenly gets less fuel than it’s used to, it can make you feel a bit sluggish for a little while.

Changes in Blood Sugar Levels

This medication also helps to keep your blood sugar levels nice and steady. If your body was used to having higher blood sugar, this new, healthier balance can feel like an energy dip at first. Your body just needs a little time to get used to this new normal.

Your Body is Adapting

At the end of the day, your body is getting used to a new and effective medicine. Any time your body has to adapt to something new, it can use a little extra energy. This can leave you feeling more tired than usual.

How Common is Fatigue and How Long Does It Last?

Feeling tired is a common side effect, but the good news is that it is usually temporary. Most people notice it the most when they first start the medication. You might also feel it for a few days after your doctor increases your dose. For most people, this tiredness gets much better or goes away completely within the first few weeks.

As your body adjusts, your energy usually comes back. In fact, many people find they have even more energy in the long run as they lose weight. So, while the answer to “does semaglutide make you tired” can be yes, it’s not a forever feeling.

Practical Tips to Boost Your Energy on Semaglutide

While your body is adjusting, there are many simple things you can do to fight fatigue. These easy tips can help you feel more like yourself again.

Prioritize Hydration

Sometimes, you feel tired simply because you are a little dehydrated. Other side effects like nausea can make it hard to drink enough. Try to sip water all day long to stay hydrated and keep your energy up.

Focus on Nutrient-Dense Foods

Since you are eating less, it’s important to make every bite count. Focus on foods that are packed with good stuff like protein, fiber, and healthy fats. Eating smaller, healthy meals throughout the day can give you a steady stream of energy.

Gentle Movement is Your Friend

It might sound strange, but a little bit of light exercise can actually give you more energy. You don’t need to run a marathon. A short, gentle walk can do wonders for waking up your body and mind.

Listen to Your Body and Rest

Don’t try to be a superhero and push through the tiredness. If you feel you need a rest, take one. A short nap or going to bed a little earlier can help your body recover and adapt.

This feeling is a normal part of the adjustment period, and it is very manageable. As your body gets used to the medicine and you start feeling the benefits of weight loss, you will likely find you have more energy than ever before.

Important Medical Information and Disclaimers

Medical Disclaimer

This content is for educational purposes only and should not be considered medical advice, diagnosis, or treatment guidance. The U.S. Food and Drug Administration (FDA) has not approved compounded semaglutide for weight management or any other use. Now that the national shortage has ended, federal law generally prohibits pharmacies from compounding products that are essentially copies of FDA-approved medications such as Wegovy. Compounded semaglutide may carry risks related to safety, quality, and dosing accuracy because it does not undergo FDA review for safety, effectiveness, or manufacturing standards. Always consult a qualified healthcare provider before starting or continuing any semaglutide treatment, and obtain prescriptions only for FDA-approved medications dispensed through licensed pharmacies.

Individual Results May Vary

Weight management outcomes with semaglutide can differ significantly from person to person. Clinical trial data may not predict real-world experiences. Factors that influence results include:

  • Consistency with prescribed medication use
  • Dietary habits and exercise routines
  • Metabolic differences
  • Other underlying health conditions
  • Concurrent medications

No specific outcome or result can be guaranteed.

Important Safety Information

The most commonly reported side effects of semaglutide include:

  • Nausea
  • Vomiting
  • Diarrhea
  • Constipation
  • Stomach pain
  • Decreased appetite
  • Indigestion
  • Belching or gas
  • Injection site reactions

These side effects are often mild and may lessen over time. Before starting semaglutide, inform your healthcare provider about all medical conditions, allergies, and medications you are currently taking. Ongoing clinical monitoring is recommended during treatment.

Warning: Semaglutide carries a boxed warning regarding the potential risk of thyroid C‑cell tumors. Do not use semaglutide if you or a family member has a history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).

Adverse Event Reporting

If you experience negative side effects from any prescription medication, you are encouraged to report them to the U.S. Food and Drug Administration (FDA) through the MedWatch Adverse Event Reporting Program or by calling 1-800-332-1088.
