Semaglutide Side Effects in the First Week:

When you first begin taking Semaglutide, it’s common to experience a few changes as your body adapts to the medication. The side effects during the first week are often mild but noticeable. Many patients report nausea, bloating, or a feeling of fullness after smaller meals. This happens because Semaglutide slows down how quickly food leaves your stomach, which helps control appetite but can also cause digestive discomfort. Some people may also feel tired or slightly lightheaded in the beginning. This doesn’t mean the medication isn’t working, it simply reflects your body adjusting to a new rhythm. Most of the time, these early side effects improve on their own within a few days or weeks.

In the meantime, small lifestyle adjustments can make a meaningful difference.

If the tiredness continues for several weeks or begins interfering with daily routines, it’s a good idea to check in with your provider. Sometimes a small dose adjustment or additional guidance can help restore energy while still keeping your treatment plan on track.
