Effects of Cholera Bacteria on the Gut

The bacteria usually stay on the surface of the small intestine rather than invading deep into the bowel. Their toxin changes how intestinal cells move chloride and other electrolytes. Water follows these particles into the gut, so the bowel contents become very liquid and pass quickly.

This fluid loss can remove salts that the nerves, muscles and heart need to work properly. A person may develop thirst, a dry mouth, weakness, dizziness, reduced urination or drowsiness. Cholera diarrhoea is often described as pale, watery stool, but appearance alone cannot confirm the cause.

Start replacing lost fluid with properly prepared oral rehydration solution while arranging urgent medical advice. It supplies water and salts in proportions that help the intestine absorb fluid. Plain water alone may not replace the electrolytes being lost, and homemade mixtures can contain too much or too little salt.

Keep taking small, frequent sips if nausea is present. A clinician may test a stool sample, assess hydration and prescribe treatment when appropriate. Severe dehydration may require IV Fluid Therapy in a healthcare setting. Avoid preparing food for other people while diarrhoea continues, and wash hands carefully after using the toilet.

Seek urgent medical care for sudden, repeated watery diarrhoea, especially after unsafe water or food exposure, travel, or contact with someone who has cholera. Go immediately if you cannot keep fluids down, feel faint or confused, pass very little urine, have marked weakness, or notice fast breathing or a racing heartbeat.

Children, older adults, pregnant people and anyone with a long-term illness can become dehydrated quickly. Do not wait for thirst to become severe before seeking help. If a person is drowsy, collapses or cannot drink, call emergency services and do not try to give drinks to someone who cannot swallow safely.

Ask whether testing is needed, how to monitor hydration at home, which rehydration solution to use, and whether medicines or observation in a clinic are appropriate for your symptoms and health history.
