Dehydration Dehydration is a condition that occurs when the loss of body fluids, mostly water, exceeds the amount that is taken in. With dehydration, more water is moving out of our cells and bodies than what we take in through drinking. Symptoms Extreme thirst Less frequent urination Dark-colored urine Fatigue Dizziness Confusion Proteinuria People with proteinuria have urine containing an abnormal amount of protein. The condition is often a sign of kidney disease. Symptoms Large amounts of protein in your urine may cause it to look foamy in the toilet. Type 2 Diabetes Type 2 diabetes develops when the body becomes resistant to insulin or when the pancreas stops producing enough insulin. Exactly why this happens is unknown, although genetics and environmental factors, such as excess weight and inactivity, seem to be contributing factors. Symptoms Increased thirst and frequent urination Increased hunger Weight loss Fatigue Blurred vision Slow healing sores or frequent infection Areas of darkened skin Kidney Stones Kidney stones (renal lithiasis, nephrolithiasis) are small, hard mineral deposits that form inside your kidneys. The stones are made of mineral and acid salts.
