There are many reasons that blood can appear in urine and stools: disease, trauma, infection, tumors and anatomic abnormalities. Under normal circumstances, there should be no blood present in either system, so even the presence of a small amount can be indicative of abnormal processes occurring.

Urine normally contains no RBCS and very few WBCs. Common causes of urinary blood cells include urinary tract and genital infections, among others.

Our bodies produce various waste products that we need to expel regularly. Substances that help you urinate are generally known as diuretics, and they help your body increase its rate of urination.

Insoluble material that tends to sink to the bottom of a liquid, as in hypostasis.

Urine consists primarily of water, waste products and electrolytes filtered from the blood by the kidneys. It is typically clear and pale yellow with a slight odor. Urine composition, color and odor normally varies, often based on your diet and hydration status.

When urine becomes acidic, uric acid stones may form in the kidneys. Kidney stones cause symptoms such as pain in the back or side, burning during urination, blood in the urine and nausea. Lab tests on your urine can determine the acidity level and screen for risk factors that may cause the kidney stones.

The urinary system consists of two kidneys, two ureters to connect the kidneys to the bladder, the bladder to hold the urine and the urethra to connect the bladder to outside the body.

Your body maintains very tight control over the pH, or level of acidity, in your body. The proper pH is necessary for the biochemical reactions responsible for life to occur efficiently. Nutrients, vitamins and minerals from foods are themselves acidic or alkaline, and must be neutralized by your body.

Hematuria, or blood in the urine, can result from a number of causes, including exercise. Although hematuria is more common in long distance runners, this condition can occur after any type of prolonged, intense physical activity. In most cases, it is not cause for serious concern.

Exercising can produce a number of results, including increased muscle mass, decreased body fat, improved strength and endurance and sometimes darker urine. Often, simple dehydration results in darker urine. Pre-workout supplementation may contribute to this.

Electrolyte imbalances occur when the levels of electrolytes in your body either rise or fall to dangerous levels. Electrolytes include sodium, potassium, calcium and phosphorus. These imbalances might adversely affect kidney function and produce symptoms such as painful urination.

Protein drinks, consumed in moderation, can make up a part of a healthy and balanced diet. In addition to protein, the shakes typically provide a source of carbohydrates, vitamins and minerals to provide health and nutrition.
