How does semaglutide work?

Semaglutide imitates a human hormone produced naturally by the gut, pancreas, and nervous system. The hormone targets areas of the brain that manage appetite, create a feeling of fullness, and enhance insulin production. Semaglutide comes as a liquid solution in a single-dose injection.

Semaglutide mimics the glucagon-like peptide-1 (GLP-1), which is responsible for targeting the areas of the brain that regulate appetite and food intake. The gut naturally produces GLP-1 in response to food. The hormone causes reduced appetite and the release of insulin. Your body creates and releases insulin in a feedback loop in response to your blood sugar level. Insulin enables your cells to convert glucose to energy. Insulin maintains the amount of glucose within your bloodstream and releases glucose to ensure an appropriate balance for your body’s metabolic needs. 

What are the common side effects of semaglutide?

During medical trials, some patients experienced nausea, vomiting, constipation, indigestion, diarrhea, belching, gas buildup, and low blood sugar among patients with type 2 diabetes, headaches, fatigue, dizziness, heartburn, and abdominal pain. Some patients also experienced gastroenteritis and gastroesophageal reflux disease. A few patients experience gallstones, pancreatitis, and kidney damage related to dehydration. 

Despite the side effects, semaglutide is FDA-approved as it is proven effective and safe for individuals who experience blood sugar concerns, excessive weight gain, and chronic weight-related illnesses. Available only with a prescription, this injection offers long-lasting benefits for many individuals.

Who is not a candidate for semaglutide?

Semaglutide is not appropriate for:

  • Patients with a personal or family history of medullary thyroid carcinoma.

  • Patients with a rare condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). 

  • Patients with a history of severe allergic reactions to semaglutide or its ingredients.

  • Patients who experience inflammation of the pancreas (pancreatitis), gallbladder problems (including gallstones), symptoms of pancreatitis or gallstones, low blood sugar, acute kidney injury, diabetic retinopathy (damage to the eyes & retina), increased heart rate, and suicidal behavior or thinking.

What is tirzepatide and how does it work for weight loss?

Tirzepatide is a medication primarily used for managing type 2 diabetes, but it has also shown effectiveness in aiding weight loss. It works by targeting two hormone receptors in the brain—GLP-1 and GIP—which help regulate appetite and insulin secretion. This dual action not only helps control blood sugar levels but also reduces appetite and speeds up the feeling of fullness, contributing to weight loss.

What are the common side effects of taking tirzepatide?

Common side effects of tirzepatide include nausea, diarrhea, decreased appetite, vomiting, constipation, and abdominal pain. These side effects are generally mild and tend to decrease over time as the body adjusts to the medication. However, it’s important to discuss any persistent or severe symptoms with a healthcare provider.

How effective is tirzepatide in weight loss compared to other treatments?

Tirzepatide has been found to be highly effective for weight loss, often resulting in a reduction of up to 24% of body weight in clinical trials. This makes it one of the more potent weight loss drugs available, especially compared to other GLP-1 receptor agonists. Its effectiveness can vary from person to person, and it is most beneficial when combined with lifestyle changes such as diet and exercise.
