Mucus in urine
Mucus is a colloid formed in the body to protect sensitive linings and can be found in various bodily organs including the large intestine, the stomach, the nose, and the lungs. Mucus is produced by the mucous membrane, which is also found in several parts of the body. In the large intestine, mucus coats the inner wall and provides lubrication so stool can be easily eliminated. Typically, urine is a clear fluid, but it can appear cloudy if any mucus has entered.
Causes of Mucus in Urine
Urinary tract infection: Mucus can appear in urine due to a bacterial infection in the urinary system. The urinary system is made up of the kidneys, bladder, ureters, and urethra. While any of these components may be affected by an infection, the bladder is usually the first to be reached, after which the bacteria will spread to other parts of the system. A common symptom of a urinary tract infection is discomfort during urination.
Irritable Bowel Syndrome: Irritable bowel syndrome is a type of gastrointestinal disorder that affects and temporarily damages the large intestine. It causes the mucous membrane in the intestine to increase mucus production. The excess mucus created may reach the urethra and become visible in the urine.
Sexually Transmitted Disease: The most common type of infection to cause problems of mucus in urine is either gonorrhea or chlamydia. Mucus discharge from the urethra can be detected in the urine and turn it yellow rather than clear.
Urachal Cancer: Also called bladder cancer, urachal cancer occurs when cells grow unrestricted in the bladder. It is a malignant form of cancer, of which a symptom is abnormal urine output. Urachal cancer can be diagnosed with a test of a urine sample. These tests show mucus in the urine, and doctors often regard the presence of mucus in urine as a key symptom of bladder cancer.
Ulcerative Colitis: In ulcerative colitis, the mucous membranes in the large intestine are damaged and produce abnormal amounts of mucus. A common symptom of ulcerative colitis is the formation of ulcers, shown by an inflamed mucous membrane. The ulcers develop on the membrane and create a yellow mucus that accumulates in the urethra and is expelled in urine.
Kidney Stones: A recent report has shown that people suffering from kidney stones have an excess of mucus in their urine. The urine was also foul-smelling and had a dark yellow color. Cloudy urine that contains mucus may therefore signify kidney stones or another obstruction in the urinary system. Kidney stones also cause severe cramps and abdominal pains. In some cases, the kidney stones can only be removed with surgery.
