Answer

Watery diarrhea [19] accompanied by an electrolyte imbalance leads to asthenia, confusion, and exhaustion. These problems are typical of patients with proctosigmoid tumors (both benign and malignant) and of medullary thyroid carcinomas (MTCs) that produce several prostaglandins (PGs; especially PG E2 and F2) that lead to malabsorption and, consequently, unavailability of nutrients.
