Ozempic & Scurvy: Weight Loss Drugs Linked to Nutrient Deficiency
A rare resurgence of scurvy, a disease historically linked to nutritional deficiencies in sailors, is being observed in some patients undergoing treatment with popular weight loss drugs like Ozempic, researchers have found.
The condition, largely absent in developed nations for decades, is emerging as a potential side effect not of the medications themselves, but of the significant dietary changes they induce, according to a review of clinical trials led by researchers at the University of Newcastle in Australia. The findings, initially reported in February 2026, have prompted concern among dietitians and medical professionals.
Amanda Kann, medical director at The Wellness Drip in West Springfield, Massachusetts, emphasized that the medications – GLP-1 receptor agonists – are tools, not cures. “It’s not the medication. It’s that they’re not eating the right food,” Kann explained. “These medications are a tool in your toolbox. They are not an automatic result guaranteed, so they’re going to help you lose the weight, but what you do still really matters.”
GLP-1 drugs work by suppressing appetite, which can lead to reduced food intake. Researchers warn that without careful attention to nutrient intake, patients may develop deficiencies. “And so, what you eat matters more,” Kann added. “We talk about eating nutrient-dense foods, eating high-protein fruits, vegetables, those sorts of things, prioritizing eating those first. So, that way, we can avoid these nutritional deficiencies before they start.”
A systematic review of 41 clinical trials encompassing 50,000 participants, conducted by the University of Newcastle team, highlighted the lack of comprehensive nutritional assessment in many trials of GLP-1 and GIP receptor agonist medications. The study, published in February, underscored the importance of addressing potential malnutrition risks.
Although cases remain rare, the re-emergence of scurvy has been documented in several countries, including Australia and the United Kingdom. British pop singer Robbie Williams was reportedly diagnosed with scurvy last year after using injectable weight loss medication, according to reports in the New York Post.
Symptoms of nutrient deficiencies can include unusual fatigue, easy bruising, and, in severe cases, hair loss. The Wellness Drip offers vitamin injections and IV drips as part of its weight loss programs, designed to bypass digestive issues and deliver nutrients directly into the bloodstream for patients experiencing appetite suppression or nausea.
Experts recommend that individuals considering or currently using GLP-1 medications consult with a medical provider to ensure adequate nutritional intake and prevent deficiencies. The Advisory Board has similarly issued guidance on the potential for nutritional deficiencies in patients using these drugs.
