GLP-1 weight-loss medicines: doctor-led assessment and follow-up
GLP-1 medicines are prescription medicines that act like a natural gut hormone to reduce appetite, help you feel full sooner and lower blood sugar. They are used for type 2 diabetes and, for some people, for weight management. At Medcare in Bongaigaon, Dr. Tamoghna Das assesses whether these medicines are suitable for you, checks for safety, and follows you up closely if you start one. Medcare does not sell medicines.

Why a doctor's assessment matters
These medicines are effective for many people, but they are not simple weight-loss shots. They affect digestion, sugar, fluid balance and muscle. They interact with diabetes medicines. They also cost money every month, and weight often returns when they are stopped. A careful assessment makes sure the benefits are likely to be worth it for you.

Dr. Das decides if a medicine is right for you after examining you and checking your tests. Many people do well with diet, activity and other care first.
Common side effects
- Nausea, especially in the first weeks or after a dose increase
- Feeling full quickly, reduced appetite
- Constipation, diarrhoea, bloating or burping
- Tiredness
These are usually mild and settle over time. Eating smaller meals, stopping when full, avoiding fried and heavy food, and drinking enough water help.
Less common but important: gallstones, inflammation of the pancreas, dehydration leading to kidney strain, and low sugar when used with insulin or some diabetes tablets. This is why follow-up matters.
Buy only what is prescribed
Use only a medicine prescribed for you, bought from a licensed pharmacy with a bill. Do not buy injections online without a prescription, from social media sellers, or from anyone offering "weight-loss injections" without a doctor's check. Fake and wrongly stored products have been reported and can be dangerous.
When to see a doctor urgently
Stop the medicine and seek care the same day, or call 108 or 112, if you have: severe stomach pain that does not go away, especially if it spreads to the back; repeated vomiting; signs of dehydration such as very little urine, dizziness or confusion; yellow eyes or skin; or swelling of the face or throat with difficulty breathing.
FAQs
Is it an injection?
Most GLP-1 medicines are given as a small injection under the skin, once a week or once a day, using a thin pen needle. Some forms are tablets. Dr. Das will explain which form suits you and teach you how to use it. Most people find the injections easy after the first try.
Will I have to take it for life?
Not necessarily, but many people regain weight after stopping. Obesity is a long-term condition, so some people need longer treatment while others stop after building strong food and activity habits. The plan is reviewed regularly, and decisions about stopping are made together with Dr. Das.
Is it safe if I have diabetes?
GLP-1 medicines are widely used in type 2 diabetes and can help both sugar and weight. If you also take insulin or certain sugar tablets, the doses may need to be lowered to avoid low sugar. Close follow-up in the first months is important.
How much weight will I lose?
Results vary a lot between people, and nobody can promise a number. Weight loss depends on the medicine, the dose, your food and activity changes, and your body. Dr. Das will set realistic health goals, such as better sugar, BP or liver tests, alongside weight.
Can I take it if I am planning a pregnancy?
No. These medicines are not used in pregnancy or while breastfeeding, and they are usually stopped some weeks before trying to conceive. If you are planning a pregnancy, tell Dr. Das so he can suggest a safe plan.
Do I still need to diet and exercise?
Yes. The medicine makes it easier to eat less, but what you eat still matters. Enough protein and regular strength exercise help keep muscle. Habits built during treatment also help you keep weight off if the medicine is stopped later.
Can I buy it online without seeing a doctor?
Please do not. GLP-1 medicines are prescription-only for good reasons: they need safety checks, dose adjustment and follow-up. Products sold without prescription, online or through social media, may be fake, wrongly stored or the wrong strength.
Does Medcare sell these medicines?
No. Medcare does not sell medicines. If a medicine is prescribed, you can buy it at a licensed pharmacy of your choice.
