From the Guidelines
Patients starting on semaglutide should undergo baseline and regular monitoring, including blood work, to ensure safety and effectiveness, with a focus on renal function, liver function, pancreatic enzymes, and thyroid function, as recommended by the most recent guidelines 1. When initiating semaglutide therapy, baseline measurements should include:
- HbA1c
- Fasting blood glucose
- Renal function tests (eGFR, creatinine)
- Liver function tests
- Pancreatic enzymes (amylase, lipase)
- Blood pressure
- Heart rate
- Weight This initial assessment helps identify potential risks and establishes a baseline for future comparisons.
After starting semaglutide, follow-up monitoring should occur at 1-3 months, then every 3-6 months, including:
- HbA1c
- Renal function
- Weight assessment Patients with pre-existing renal impairment require more frequent monitoring of kidney function, as recommended by the American College of Cardiology 1. Additionally, patients should be monitored for:
- Gastrointestinal side effects
- Hypoglycemia (especially if on concurrent insulin or sulfonylureas)
- Signs of pancreatitis or gallbladder disease Thyroid function tests are recommended for patients with thyroid disorders, as GLP-1 receptor agonists may affect thyroid C-cells 1. Regular monitoring and patient education are crucial to minimize the risk of adverse effects and optimize the benefits of semaglutide therapy, as emphasized in the 2022 clinical practice guideline on pharmacological interventions for adults with obesity 1.

From the Research
Monitoring for Patients Starting on Semaglutide
To ensure safe and effective treatment with semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, several monitoring parameters are essential. These include:
- Blood Work: Regular monitoring of HbA1c levels to assess glycemic control, as well as measurements of body weight, blood pressure, and heart rate 2, 3, 4.
- Glycemic Control: Monitoring for signs of hypoglycemia, although the risk is generally low with semaglutide 5, 3, 4.
- Gastrointestinal Side Effects: Patients should be monitored for gastrointestinal adverse effects such as nausea, vomiting, and diarrhea, which are common with semaglutide 2, 5, 4.
- Pancreatic Safety: Although the risk is considered low, monitoring for pancreatitis is recommended, especially in patients with a history of pancreatitis 5, 4.
- Thyroid Cancer: Semaglutide is contraindicated in patients with a history of medullary thyroid cancer, and caution is advised in patients with a history of thyroid cancer 6.
- Diabetic Retinopathy: Patients with diabetic retinopathy should be carefully monitored, as semaglutide may increase the risk of complications 5, 4.
- Cardiovascular and Renal Monitoring: Given the potential benefits of semaglutide on cardiovascular and renal outcomes, monitoring of these parameters may also be relevant 6.
Key Considerations
- Semaglutide has been shown to be effective in reducing HbA1c levels and promoting weight loss, with a relatively low risk of hypoglycemia 2, 3, 4.
- The safety profile of semaglutide is generally consistent with that of other GLP-1 receptor agonists, with gastrointestinal side effects being the most common adverse events 5, 4.
- Regular monitoring and follow-up are essential to ensure the safe and effective use of semaglutide in patients with type 2 diabetes 2, 5, 3, 6, 4.
