| Label | Value |
|---|---|
| Known heaviest weight | 20 stone (127 kg) (LADbible) |
| Weight lost total | 3.5 stone (22 kg) (LADbible) |
| Weight lost on jabs | 8 kg (1 stone 4 lb) (LADbible) |

How much weight has Gemma Collins lost?
Collins reported a total weight loss of 3.5 stone (22 kg), achieved through a combination of diet and the prescription drug Mounjaro. According to her comments on I’m A Celebrity South Africa, she lost roughly 8 kg (1 stone 4 lb) from the injections alone, going from a size 26 to a size 20 in three months (LADbible).
- Total loss: 3.5 stone (22 kg) – includes diet and medication
- Jabs-only loss: 8 kg (1 stone 4 lb) – self-reported on Mounjaro
- Timeframe: three months for the size drop; total timeline spans part of 2025 into early 2026
The implication: self-reported weight loss data should be interpreted with caution, especially when tied to prescription drugs.
Did Gemma Collins lose weight on Mounjaro?
Yes. Collins confirmed she used Mounjaro (tirzepatide), a once-weekly injection approved for weight management and type 2 diabetes by the NHS. She told Seann Walsh that she worked up to the 15 mg dose before pain began a few weeks later (LADbible). The weight loss on the drug alone accounted for roughly a quarter of her total reduction.
Is Gemma Collins still using Mounjaro?
As of April 2026, she had paused use because of a gall bladder attack. She described having “a small gallbladder attack” and needing to “slow down on it all for a bit” (LADbible). No public statement has confirmed whether she restarted.
Collins’s pause exemplifies a known risk: the NHS lists gallstones as a possible serious side effect of tirzepatide, and the Eli Lilly U.S. Prescribing Information (manufacturer) warns of acute gallbladder disease. Users should be alert to sudden abdominal pain.
The pattern: Collins’s story highlights the need for patients to monitor for gallbladder symptoms when using GLP-1 medications.
Why did Gemma Collins stop Ozempic?
Strictly speaking, Collins did not stop Ozempic – she used Mounjaro, not Ozempic (semaglutide). However, the question reflects a common conflation of GLP-1 drugs. Collins stopped Mounjaro after developing gall bladder symptoms. She told the Daily Mail (as cited by LADbible) that she had “a small gallbladder attack” and that a home scan revealed gallstones. The NHS advises anyone on tirzepatide to seek urgent help if they experience severe stomach pain that does not go away.
Did Gemma Collins experience side effects?
Yes, a gall bladder attack was the primary side effect. She also mentioned pancreatitis – the NHS lists acute pancreatitis as another serious risk. The FDA label (U.S. regulator) similarly notes that pancreatitis has been observed in clinical studies and recommends discontinuation if suspected.
While celebrities can inspire weight-loss journeys, their individual responses – including rare side effects like gallstones – are not representative of the average user. For every person who loses 3.5 stone, another may face complications that require stopping treatment.
What this means: the individual nature of side effects underscores the importance of medical supervision.
What was Gemma Collins’ heaviest weight?
Collins has publicly referenced a heaviest weight of around 20 stone (127 kg). The figure appears in multiple interviews from 2025–2026, including her discussions on I’m A Celebrity (LADbible). Her weight fluctuated over the years, but the 20-stone mark is the highest she has disclosed.
- Heaviest reported: ~20 stone (127 kg)
- Current weight (April 2026): not explicitly stated, but after losing 3.5 stone she would be around 16.5 stone (105 kg)
- Size change: from 26 to 20 in three months
The catch: weight fluctuations and self-reported figures make it difficult to pin down exact metrics without clinical records.
Which celebrity used Ozempic to lose weight?
Several celebrities have publicly acknowledged using GLP-1 medications for weight loss. Below are notable examples.
| Celebrity | Drug | Outcome | Source |
|---|---|---|---|
| Gemma Collins | Mounjaro (tirzepatide) | Lost 3.5 stone, paused after gall bladder attack | LADbible |
| Jeremy Clarkson | Ozempic (semaglutide) | Quit due to side effects (gastrointestinal) | The Sunday Times (UK newspaper) |
| Elon Musk | Ozempic / Wegovy | Lost ~30 lb, shared on X | Public X posts (2022) |
The pattern: celebrity endorsements raise awareness but often skip the side-effect warnings. Collins’s story, in particular, adds a cautionary voice to the narrative.
While celebrities can inspire weight-loss journeys, their individual responses – including rare side effects like gallstones – are not representative of the average user. For every person who loses 3.5 stone, another may face complications that require stopping treatment.
The implication: celebrity experiences can skew public perception of drug risks and benefits.
