Mounjaro, Ozempic, Wegovy - The Weight Loss Revolution

 From Diabetes Treatment to Weight Loss Revolution

India is undergoing a significant transformation in metabolic health particularly a sharp rise in cases of diabetes and obesity. This can be attributed mainly to modern lifestyles. On the flip side, today, social media strongly emphasizes good looks and healthy lifestyle. This increased the interest in weight-loss treatments. Fortunately, new treatments, awareness programs and medical advances are changing how these metabolic issues are dealt with.

Power Drugs

March 2025 marked the launch of the breakthrough drug Mounjaro (Generic name: Tirzepatide) in India. Mounjaro is a prescription medication used primarily to treat Type 2 Diabetes.

How Mounjaro Works

Mounjaro activates two important hormones in the body:

• GLP-1 (glucagon-like peptide-1)
• GIP (glucose-dependent insulinotropic polypeptide)

This dual-hormone action enhances blood sugar regulation and suppresses appetite, supporting weight loss. By September it had become one of India’s top-selling branded drugs because of the high demand for diabetes and obesity treatment. Since its approval by the U.S. Food and Drug Administration in 2022, Mounjaro has emerged as one of the most promising therapies for metabolic diseases.

Ozempic Launched

December 2025 saw the launch of Ozempic in India. It is available in 0.25 mg, 0.5 mg and 1mg doses. This prescription drug typically costing approx. Rs 8800 to 11175 per month. It is approved by the Central Drugs Standard Control Organization (CDSCO) for adults with type 2 Diabetes.

How Ozempic Works

Ozempic contains Semaglutide. Unlike Mounjaro, it mimics only GLP-1, which plays a key role in regulating blood sugar levels and appetite. By stimulating insulin production, slowing digestion, and reducing hunger, it often leads to substantial weight loss.

Originally developed for people with Type 2 Diabetes, Ozempic attracted global attention due to its unexpected effects - Significant weight loss. However, there is lot of controversy surrounding Ozempic because of its use for weight loss rather than diabetes treatment. In many countries, the drug has become popular among celebrities and social media influencers who are seeking rapid weight reduction.

Scene Stealer Wegovy

But it raises a question! Ozempic was launched internationally in December 2017 while Mounjaro had an international launch in May 2022. Then why was Ozempic launched in India after Mounjaro?

This was primarily to manage global supply shortage. The global demand for Ozempic was extremely high so they wanted to ensure a stable supply before entering a huge market like India. This way the patients would not start treatment and then have to deal with shortages.

Also, the manufacturers wanted to prioritize the introduction of their weight loss-specific drug Wegovy in India first rather than focusing initially on the diabetes-focused Ozempic.

Advantage Mounjaro

Thus, their competitor launched Mounjaro and took an early share of the market in India, To counter this, Ozempic entered the Indian market with a competitive lower-priced strategy. Typical monthly cost of Mounjaro is between 13,000 to 25,000 while that of Ozempic ranges from Rs 9000 to 20,000 and Wegovy is Rs 10000 to 17000 per month.

But there is a heavier price too!

Many people experience mild digestive side effects like Nausea, Diarrhea, Vomiting, Constipation, Stomach discomfort and Loss of appetite. Most of these symptoms improve as the body adjusts to the medication. Doctors usually start patients on lower doses and gradually increase them.

Rare but serious side effects

• ·        Pancreatitis
• ·         Gallbladder disease
• ·         Kidney problems
• ·         Severe allergic reactions

Hence for safe use, it should always be prescribed and monitored by a healthcare professional.

Figures from studies suggest the following average weight loss:

• Mounjaro - 15–22% body weight loss
• Wegovy - 12–15% body weight loss
• Ozempic - 8–12% body weight loss

However, the results vary depending on:

• Lifestyle
• Diet
• Physical activity
• Dosage

Celebrity Favourite

Some celebrities rumored to have used Ozempic or similar drugs include Elon Musk, Kim Kardashian and Oprah Winfrey, to name a few. Bollywood personality Karan Johar is being ridiculed for having an ‘Ozempic Face’. Many other international celebrities and Bollywood personalities have not officially confirmed using these medications specifically. The list of celebrity users coupled with the cost of the medications places it in the elite class of drugs. This raises questions about healthcare inequality.

Looking Ahead

To end on a positive note, the most significant development is the expiry of the semaglutide patent on March 20, 2026. This will lead to the emergence of generic Ozempic from domestic pharma giants. Over 50 Indian companies like Sun Pharma, Zydus Lifesciences, Dr. Reddy’s and Lupin have received approval to launch their own versions. New generics are expected to enter the market at Rs   3,500 to 5,000, making the treatment accessible to a much larger segment of the population.

 Osteoporosis – The Silent Thief

We all know that calcium is required for strong bones. But so are other vitamins and minerals. Read on…

Bones form the framework of the body and help in movement. With age, they become weak and fragile increasing the chances of fracture with or without injury. While Diabetes is called a Silent Killer and a lot of awareness is generated about it, Osteoporosis is a Silent thief as it steals Calcium from your bones and makes bones porous.

Osteoporosis

Osteoporosis deserves great attention to avoid mobility issues. This will reduce the suffering of the elderly population especially females. Calcium is the foremost mineral that comes to mind while referring to bones. It helps to make bones dense.

About 99% of calcium is in your bones and teeth and 1% is in the blood (serum calcium). Serum calcium helps in muscle contraction, beating of heart and clotting of blood. When serum calcium falls, there is removal of calcium from the bones to maintain the levels.

Calcium Requirement

The daily requirement of calcium for women up to 50 years and men up to 70 years is 1000 mg/day while for women above 50 and men above 70 years is 1200 mg/day. Why the difference in calcium requirement?

The reason is osteoporosis affects women more than men. A study in Delhi estimated its prevalence in men as 24.6% as against 42.5% in men. Osteoporosis has affected 100 million women worldwide – approx. one-tenth of women at 60, one-fifth at 70, two-fifths at 80 and two-thirds at 90. This is because there is a rapid decline in bone mass density after menopause.

Exercise and Lifestyle

However, while it is more predominant in women, it can also affect children and adults with hormonal imbalances, thyroid or on crash diets. Along with a proper balanced diet, weight bearing exercises like jogging, walking, climbing up and down the stairs and resistance training helps in its prevention. Lifestyle modifications, avoiding alcohol and smoking also make a big difference.   

We lose calcium through sweat, urine and faeces in day to day life. It is important for the body to maintain its calcium levels for smooth functioning. Our body does not make calcium. Therefore it is important to obtain calcium through our diet. Otherwise one has to resort to supplements. 

Calcium Sources

We are all aware of milk and other dairy products as rich sources of calcium. But are they the only sources? Soya and its products, dark green leafy vegetables such as moringa and radish leaves, almonds, walnuts, sesame and garden cress seeds, fermented ragi products, sardines, Chinese cabbage and broccoli are some other sources.

Other Vitamins and Minerals

However, we cannot forget the importance of other vitamins and minerals that help the body to absorb and utilize calcium; the foremost being Vitamin D, the Sunshine vitamin.

The other important vitamins are B5, B6, B9, B12 and K2. The minerals phosphorus, magnesium, manganese, zinc, potassium, Boron and silica all have key roles in bone strengthening.
