Weight Loss Jab Side Effects: Understanding the 'One in 10' Risk
Individuals using weight loss jabs may face several side effects that occur in approximately "one in 10" users, according to health experts. These medications, also known as GLP-1 inhibitors, have surged in popularity due to their effectiveness in managing blood sugar levels for diabetic patients and aiding weight loss. Available as injections, some are accessible through the NHS for eligible patients. However, awareness of potential side effects is crucial, as not everyone will experience them, but issues can be very common.
Common Digestive Problems and Other Less Serious Effects
It is very common for people taking these jabs to encounter digestive issues, such as nausea, diarrhoea, constipation, and stomach pain. The British Heart Foundation (BHF) notes that these side effects affect one in 10 individuals, based on patient leaflets for medications like Mounjaro and Wegovy. Additionally, the injections can lead to tiredness, dizziness, hair loss, low blood sugar, and a fast heart rate in some cases. If you experience any of these symptoms, consulting a doctor is advised, as dosage adjustments or discontinuation might be necessary.
Rarer but Serious Risks: Acute Pancreatitis and Vision Loss
In rarer instances, users could be at risk of acute pancreatitis, an inflamed pancreas that affects up to one in 100 people on these jabs. Symptoms include a sudden severe pain in the middle of the abdomen, and immediate medical attention from a GP or via 111 is recommended. Furthermore, the Medicines and Healthcare products Regulatory Agency (MHRA) has warned that very rarely, semaglutide (the non-brand name for Wegovy) can cause a sudden deterioration in eyesight, leading to full or partial vision loss, typically in one eye at a time. Urgent medical care and referral to a specialist eye doctor are essential if this occurs.
Nutritional Concerns and Contraceptive Implications
Due to the appetite-suppressing nature of these drugs, reduced food intake can increase the risk of poor nutrition. The BHF highlights that rapid weight loss may also reduce muscle and bone mass. To mitigate this, maintaining a healthy balanced diet with small, regular meals rich in lean protein, calcium, and vitamin D, along with regular exercise, is important. Additionally, the MHRA cautions that Mounjaro may lower the effectiveness of the contraceptive pill, advising the use of non-oral alternatives like condoms. Weight loss injections should not be used during pregnancy, while trying to conceive, or while breastfeeding.
If you encounter any side effects from these medications, it is vital to speak with a GP promptly to ensure safe management and care.
