Liver cirrhosis, a destructive process resulting from fibrosis of liver tissue, is most commonly due to toxic substances (alcohol) or viral infections (hepatitis). Complications include bleeding from the esophagus or stomach, impaired blood coagulation, accumulation of fluid in the abdomen and impaired ability to detoxify medications.
If otherwise fit, divers who, have a normal response to exercise, can dive if they have mild cirrhosis, with no symptoms or secondary complications. Before diving, they should be evaluated by their physicians. In cases where cirrhosis is more severe, the rigors of scuba and the effects of the disease could impair a diver’s ability. In such cases, scuba is not recommended.
