Semaglutide is typically used for treating type 2 diabetes and other medications designed to help with weight loss. Among others, it is found in Wegovy, Ozempic, and Rybelus, three popular treatments in the United States.
While most of the side effects can be categorized as mild, recent studies and experiences have shown that some patients can have severe reactions to semaglutide, sometimes leading to life-changing circumstances.
This article will explore the range of known side effects stemming from the use of semaglutide in medication and also cover what to do if you, as a patient, have been affected by a more severe complication due to your treatment.
Mild Side Effects
Typically the side effects have been classified as either mild or severe when it comes to semaglutide. Below, we have gathered a list of the known symptoms patients can experience when using Wegovy, Ozempic, or Rybelus.
While these symptoms can be difficult to deal with in their own right, they are considered mild due to the fact that they do not require medical attention and will typically pass in a short time. However, they can still be worth knowing about, as some people will react worse than other patients.
- Heartburn
- Nausea
- Headaches
- Diarrhea
- Stomach pain
- Constipation
Severe Side Effects
On the more serious issues, semaglutide is known to cause gastrointestinal issues that can be dangerous for the patient. While not directly life-threatening, the side effects can lead to other complications if left untreated, some of which can, in fact, be life-threatening.
Gastroparesis
Gastroparesis, also known as stomach paralysis, is a condition in which the nerves and muscles of the patient are severely affected and weakened.
This weakening will negatively impact the overall function of your stomach, leading to slower digestion, with food not being processed as nature intended. For patients with type 2 diabetes, this can cause other issues, such as further difficulty controlling blood sugar levels.
Gastroparesis can cause many of the other symptoms listed above, such as vomiting, bloating, nausea, and more. While few patients report that it is outright painful, it can still greatly impact the daily lives of those affected.
Ileus
Patients using Wegovy, Rybelsus, or Ozempic can also experience Ileus, which is also referred to as blocked intestines or bowel obstruction and can be particularly difficult for type 2 diabetes patients. It is typically categorized as either a partial or complete obstruction of the bowels, requiring different treatments depending on the severity.
Both conditions are serious and will require medical attention, although partial obstructions can be dealt with more easily and often without invasive operations. A complete obstruction of the bowels may require enemas, surgery, or nasogastric suction to alleviate the patient of the issue.
Patients using Wegovy, Rybelus, or Ozempic are often type 2 diabetes patients, and as such, it is also important to recognize that Ileus can make it more difficult for the body to control the glycemic levels, thereby increasing the risk of other issues.
