GLP-1 Drugs: A Breakthrough with Risks
The Indian Ministry of Health and Family Welfare recently emphasized that Glucagon-like peptide-1 receptor agonists (GLP-1 drugs) represent a significant medical breakthrough for treating type 2 diabetes and obesity, but they are not without risks. These drugs can cause a wide range of side effects, from common nausea and vomiting to severe complications like pancreatitis, kidney injury, and bowel obstruction. Therefore, GLP-1 drugs must only be taken under the supervision of a registered medical practitioner/specialist, and patients should obtain them only with a valid prescription.
Indian regulatory authorities have taken firm steps to prevent unsupervised use and malpractice in the supply chain. The Ministry has initiated an extensive awareness campaign on this matter.
How to Prevent Diabetes and Obesity?
Diabetes is mainly categorized into type 1 and type 2. Type 2 diabetes is related to the body's ineffective use of insulin. Its risk factors include:
- Family history of diabetes
- Obesity or being overweight
- Lack of sufficient physical activity
Type 2 diabetes is preventable. Key measures to stay healthy include:
- Achieving and maintaining a healthy body weight.
- Engaging in at least 150 minutes of moderate-intensity exercise per week.
- Eating a healthy diet, avoiding sugar and saturated fats.
- Avoiding tobacco use.
Obesity is a chronic disease caused by excess body fat. For Asian populations, a Body Mass Index (BMI) ≥25 kg/m² is defined as obesity, and 23.0-24.99 kg/m² as overweight. Recommendations for preventing and reducing obesity include reducing calorie intake from fats and sugars, increasing the daily intake of fruits, vegetables, legumes, whole grains, and nuts, and maintaining regular physical activity (60 minutes per day for children and 150 minutes per week for adults).
How Do GLP-1 Drugs Work?
GLP-1 drugs treat type 2 diabetes and obesity by correcting hormonal imbalance:
- Mimicking Natural Hormone: They imitate the GLP-1 hormone produced after eating.
- Regulating Blood Sugar: They stimulate the pancreas to release more insulin and suppress glucagon, thereby lowering blood sugar levels.
- Controlling Appetite: They slow gastric emptying, increase the feeling of fullness, reduce food intake, and lead to weight loss.
Several GLP-1 medications are available on the market, such as semaglutide injection/tablets, liraglutide, tirzepatide, and others. However, misuse can lead to serious side effects ranging from nausea and dizziness to pancreatitis and medullary thyroid cancer.
Stringent Regulatory Measures
To ensure the proper use of GLP-1 drugs, the Drug Controller General of India has intensified regulatory surveillance, including:
- Restricting prescription rights to endocrinologists, internal medicine specialists, and cardiologists.
- Issuing comprehensive advisories to drug manufacturers to stop misleading advertisements and promotions that could encourage use without a prescription.
- Conducting audits and inspections across the country targeting online pharmacy warehouses, wholesalers, retailers, and weight loss clinics, and issuing notices to violators.
Key Reminder: GLP-1 drugs are prescription medications. Their use must be based on professional medical diagnosis and supervision. Do not purchase or use them through unofficial channels, as it may pose serious health risks.
