Which medical field involves the treatment and management of patients with conditions affecting their kidneys?

The field that specifically focuses on the treatment and management of patients with kidney-related conditions is nephrology. Nephrologists are specialized physicians who diagnose and treat various kidney diseases, including chronic kidney disease, acute kidney injury, and conditions that affect kidney function and structure. They also manage conditions like hypertension and diabetes that can have significant effects on kidney health.

The other fields mentioned do not focus on kidney treatment. Geriatrics primarily deals with health care for elderly patients and age-related conditions. Endocrinology is concerned with hormone-related disorders and glands, such as diabetes or thyroid issues. Cardiology focuses on diseases and conditions of the heart and cardiovascular system. This makes nephrology the correct choice for anyone seeking medical management related to kidney issues.
