Comparing Semaglutide Side Effects to Other Weight Loss Medications: What Patients Need to Know

The rising incidence of obesity and metabolic disorders has led to the development of multiple pharmacological interventions designed to support weight loss and improve metabolic health. Among these, semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, has emerged as one of the most effective modern treatments. While its clinical success is well documented, understanding its safety profile is essential when determining whether it is the right option for a patient. This discussion reviews the side effects of semaglutide and compares them to other commonly used medications, including liraglutide, orlistat, and phentermine-topiramate.

Side Effects of Semaglutide

Semaglutide regulates appetite and improves blood sugar control, which contributes significantly to weight reduction. However, like most medications, it may cause side effects. The most commonly reported are gastrointestinal symptoms, such as:

• Nausea

• Vomiting

• Diarrhea

• Constipation

• Abdominal pain or bloating

These effects are typically most noticeable in the early phases of treatment and tend to decrease as the body adjusts to the medication. Clinical evidence suggests that while about 20% of patients may experience persistent gastrointestinal discomfort, most symptoms improve with continued therapy and appropriate dose adjustments.

More serious but less common complications may include pancreatitis, gallbladder disease, and kidney injury, often secondary to severe dehydration from prolonged vomiting or diarrhea. The FDA has also issued a boxed warning noting a potential risk of thyroid C-cell tumors based on animal studies. While human risk remains unclear, semaglutide is not recommended for patients with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2.

Comparison with Other Weight Loss Medications

Liraglutide

Like semaglutide, liraglutide is a GLP-1 receptor agonist and therefore produces similar gastrointestinal side effects. Patients commonly experience nausea, vomiting, abdominal cramping, and diarrhea. While symptoms may be slightly less severe than with semaglutide in some cases, liraglutide requires daily injections, which can affect long-term adherence.

Orlistat

Orlistat works differently by blocking the absorption of dietary fat. As a result, its side effects are almost entirely gastrointestinal and often socially disruptive, including:

• Oily stools

• Uncontrolled bowel movements

• Flatulence with discharge

• Frequent bowel urgency

Although these symptoms are unpleasant, orlistat generally does not carry the risk of pancreatitis or thyroid concerns, making it less risky in terms of severe complications, but often difficult for patients to tolerate.

Phentermine-Topiramate

Phentermine-topiramate combines an appetite suppressant with an anticonvulsant. While effective for many patients, it introduces a very different side-effect profile, including:

• Dry mouth

• Insomnia

• Dizziness

• Mood changes

• Potential risk of anxiety, depression, or suicidal thoughts

These neurological and psychological risks make the medication unsuitable for certain patients and require careful monitoring.

Overall Tolerability and Clinical Considerations

Compared to these alternatives, semaglutide generally offers a favorable balance of effectiveness and safety, especially when managed under medical supervision. Although gastrointestinal discomfort is common initially, it is typically manageable with gradual dose titration, hydration, and proper patient education. Semaglutide also provides the benefit of significant, sustained weight loss and metabolic improvement, which enhances long-term adherence and overall success.
