Meds, actually.
The kidneys (and the liver as well for some) helps in cleaning your body of the excess chemicals in pills or whatever you may consume. Check the box of the meds you take to know which organ it is killing.
I used to take 2-3gr of ibuprofen when I was younger because of tooth pain before I knew how bad it really was. Never take Advil again anon.
You should also need to make extra effort of keeping your heart healthy, drink caffeine, walk, and don't eat saturated fats. If you get HBP then it's fucking over, you will be forced to take kidney destroyers until you die.
