What’s more, around 150,000 reports of non-serious adverse side-effects have been filed by patients in the UK using weight-loss medications.

It must be noted, however, that none of these fatalities are proven to have been caused directly by the game-changing .
They could have been caused by underlying or undiagnosed illnesses which are unrelated to the fat jabs.
This new data, revealed in an analysis by The Times , came from the MHRA’s Yellow Card Scheme.
The scheme allows relatives of patients, carers and medics to submit concerns over medication and report side-effects that they suspect were caused by fat jabs.
More than one report can be made per patient, however, meaning the figures do not always reflect the total number of people experiencing side-effects.
Nevertheless, the data showed that there were over 100,000 reports of adverse effects from tirzepatide – also known as Mounjaro – with around 10,000 of them classed as “serious”.
For liraglutide, of the roughly 3,000 reports of adverse reactions, 734 were described as serious.

Dr Alison Cave, MHRA’s Chief Safety Officer said at the time: “Patient safety is the MHRA’s top priority and we continually monitor the safety and efficacy of all licensed medicines.
“For the vast majority of patients who are prescribed GLP-1s, they are safe and effective medicines which deliver significant health benefits.
“The risk of developing these severe side effects is very small, but it is important that patients and healthcare professionals are aware and alert to the associated symptoms.”

Like any medication, weight loss jabs can have side effects.
Common side effects of injections include:
Nausea: This is the most commonly reported side effect, especially when first starting the medication. It often decreases over time as your body adjusts.
Vomiting: Can occur, often in conjunction with nausea.
Diarrhea: Some people experience gastrointestinal upset.
Constipation: Some individuals may also experience constipation.
Stomach pain or discomfort: Some people may experience abdominal pain or discomfort.
Reduced appetite: This is often a desired effect for people using Ozempic for weight loss.
Indigestion: Can cause a feeling of bloating or discomfort after eating.
Serious side effects can also include:
Pancreatitis: In rare cases, weight loss jabs may increase the risk of inflammation of the pancreas, known as pancreatitis, which can cause severe stomach pain, nausea, and vomiting.
Kidney problems: There have been reports of kidney issues, including kidney failure, though this is uncommon.
Thyroid tumors: There’s a potential increased risk of thyroid cancer, although this risk is based on animal studies. It is not confirmed in humans, but people with a history of thyroid cancer should avoid Ozempic.
Vision problems: Rapid changes in blood sugar levels may affect vision, and some people have reported blurry vision when taking Ozempic.
Hypoglycemia (low blood sugar): Especially if used with other medications like sulfonylureas or insulin.
Caroline’s family, however, raised concerns that doctors too readily attributed her symptoms to side effects of the jab, and potentially, that other causes were not properly investigated.

Commenting on The Times analysis, a Novo Nordisk spokesperson said: “At Novo Nordisk we care deeply about patient safety. Like all medicines, treatments used for chronic conditions can have side-effects, and these can vary from person to person.
“That is why medicines should be prescribed by, and used under the supervision of, a healthcare professional, who can consider the potential benefits and risks for each individual.
“We recommend that any patient experiencing side-effects while taking GLP-1 RA medicines report them to their healthcare provider and via the MHRA Yellow Card scheme.”
And an Eli Lilly spokesperson said: “Patient safety is Lilly’s top priority. We take reports regarding patient safety seriously and actively monitor, evaluate and report safety information for all our medicines.
