Initially developed for treating diabetes, weight loss injections like Wegovy and Mounjaro have gained popularity among 2.4 million individuals in the UK.

Regarded as a breakthrough medication, these injections have shown remarkable outcomes, allowing users to shed up to a fifth of their body weight. Besides weight loss, they offer additional benefits such as reducing the risk of heart attacks, cancer, managing addiction, and tackling depression.

Although these drugs, which imitate a hormone known as glucagon-like peptide 1 (GLP-1) to suppress hunger, are approved for NHS use, emerging side effects are a concern. Recent studies have linked weight loss injections to hair loss, with reports of vomiting and diarrhea among patients.

Here are the potential side effects to be mindful of, supported by scientific evidence:

Abruptly reducing food intake requires careful management. Earlier this year, a significant obesity conference in Istanbul issued a consensus statement cautioning users of GLP-1 drugs about the risk of malnutrition if they continue consuming junk food, even in smaller amounts.

Emphasizing the importance of maintaining dietary quality, experts recommend a sufficient intake of quality protein. Dr. Laurence Dobbie, a population health specialist at King’s College London, highlighted the necessity of prioritizing nutrient-dense foods rich in protein, fiber, and fluids.

Recent findings suggest a possible connection between weight loss medications and hair loss. Reports indicate a rare side effect of alopecia among users of weight loss jabs like Wegovy and Mounjaro, with a study revealing a higher likelihood of hair loss compared to users of different diabetes medications.

Experts suggest that hair loss may be attributed to sudden calorie reductions and nutrient deficiencies, prompting an investigation by the US FDA into this potential side effect.

Commonly reported side effects of weight loss injections include nausea, vomiting, diarrhea, and constipation, along with complaints of stomach cramps, indigestion, and bloating by some users.

To address diarrhea-related dehydration, the NHS recommends adequate fluid intake of 2-3 liters daily. While these side effects are generally manageable for many, some individuals may find them severe enough to discontinue the medication.

Severe but rare side effects include the need for gallbladder removal and acute pancreatitis, which can have fatal consequences.

Significant weight loss may lead to excess skin, commonly referred to as “Ozempic face,” “Ozempic feet,” or “Ozempic butt,” terms used to describe skin sagging or aging. Celebrities like Sharon Osbourne have openly discussed their experience with Ozempic for weight loss, highlighting potential skin changes.

The phenomenon of “Ozempic face” refers to facial hollowing and increased
