Methods Case study Discussion: Patient presented weakness, nausea and muscle pain persisting for a week. Neither did the patient report vomiting nor abdominal pain. She was conscious. Combining these clinical symptoms and examinations, a diagnosis was made that the patient was suffering from hypoosmotic hyponatremia. This prompted further investigation, resulting in the discovery of probable hypopituitarism. Conclusion This case underscores that the basic condition, which is breast cancer, and the therapy of breast cancer may lead to hypopituitarism, which causes severe hyponatremia.
