The Drug Rehabilitation Centre in Pune and the Drug Rehabilitation Centre in India states that the kidneys are a pair of bean-shaped organs present in all vertebrates. They remove waste products from the body, maintain balanced electrolyte levels, and regulate blood pressure. The kidneys are at the back of the abdominal cavity, with one sitting on each side of the spine. The Drug Rehabilitation Centre in Pune states that each kidney weighs 125–170 grams (g) in males and 115–155 g in females. Over consumption of alcohol or drugs, thus can lead to a severe kidney dysfunction in the early 50’s.
