Omega-3 fats show modest weight gain in pancreatic cancer patients

People with pancreatic cancer often struggle to keep their weight up. This is a serious problem because losing weight can make the disease harder to treat. A large review looked at nine studies to see if adding omega-3 fats, like EPA and DHA, could help. These fats are found in fish oil and are sometimes used to support nutrition. The review found that patients who took these supplements gained a small amount of body weight. This was a positive sign for people fighting this difficult illness. However, the review did not find that these fats helped build lean muscle or improve blood protein levels. Those are also important markers of health for cancer patients. The researchers were careful to note that the evidence has low certainty. Many of the studies were small, and the results varied a lot from one group to another. This means we cannot be sure if the weight gain was truly helpful or just happened by chance. The findings do not prove that these fats will improve overall nutrition or survival. Doctors should still discuss individual cases with their care teams before starting any new supplement. The current data is not enough to say these fats are a standard treatment for everyone.
