The pelvic floor is a group of muscles and other tissues that form a sling or hammock across the pelvis. In women, it holds the uterus, bladder, bowel, and other pelvic organs in place so that they can work properly. The pelvic floor can become weak or be injured. The main causes are pregnancy and childbirth. Other causes include being overweight, radiation treatment, surgery, and getting older.

Common symptoms include:

• Feeling heaviness, fullness, pulling, or aching in the vagina. It gets worse by the end of the day or during a bowel movement.
• Seeing or feeling a "bulge" or "something coming out" of the vagina
• Having a hard time starting to urinate or emptying the bladder completely
• Having frequent urinary tract infections
• Leaking urine when you cough, laugh, or exercise
• Feeling an urgent or frequent need to urinate
• Feeling pain while urinating
• Leaking stool or having a hard time controlling gas
• Being constipated
• Having a hard time making it to the bathroom in time

Your health care provider diagnoses the problem with a physical exam, a pelvic exam, or special tests. Treatments include special pelvic muscle exercises called Kegel exercises. A mechanical support device called a pessary helps some women. Surgery and medicines are other treatments.

Pelvic pain occurs mostly in the lower abdomen area. The pain might be steady, or it might come and go. It can be a sharp and stabbing pain in a specific spot, or a dull pain that is spread out. If the pain is severe, it might get in the way of your daily activities.

If you're a woman, you might feel pain during your period. It could also happen when you have sex. Pelvic pain can be a sign that there is a problem with one of the organs in your pelvic area, such as the uterus, ovaries, fallopian tubes, cervix, or vagina. If you're a man, the cause could be a problem with the prostate. In men and women, it could be a symptom of infection, or a problem with the urinary tract, lower intestines, rectum, muscle, or bone. Some women have more than one cause of pelvic pain at the same time.

You might have to have lab, imaging, or other medical tests to find the cause of the pain. The treatment will depend on the cause, how bad the pain is, and how often it occurs.

Your peritoneum is the tissue that lines your abdominal wall and covers most of the organs in your abdomen. A liquid, peritoneal fluid, lubricates the surface of this tissue.

Disorders of the peritoneum are not common. They include:

• Peritonitis - an inflammation of the peritoneum
• Cancer
• Complications from peritoneal dialysis

Your doctor may use imaging tests or lab tests to analyze the peritoneal fluid to diagnose the problem. Treatment of peritoneal disorders depends on the cause.

Your pituitary gland is a pea-sized gland at the base of your brain. The pituitary is the "master control gland" - it makes hormones that affect growth and the functions of other glands in the body.

With pituitary disorders, you often have too much or too little of one of your hormones. Injuries can cause pituitary disorders, but the most common cause is a pituitary tumor.

Your pituitary gland is a pea-sized gland at the base of your brain. The pituitary is the "master control gland" - it makes hormones that affect growth and the functions of other glands in the body.

Pituitary tumors are common, but often they don't cause health problems. Most people with pituitary tumors never even know they have them. The most common type of pituitary tumor produces hormones and disrupts the balance of hormones in your body. This can cause endocrine diseases such as Cushing's syndrome and hyperthyroidism.

Symptoms of pituitary tumors include:

• Headaches
• Vision problems
• Nausea and vomiting
• Problems caused by the production of too many hormones

Pituitary tumors are usually curable. Treatment is often surgery to remove the tumor. Other options include medicines, radiation therapy, and chemotherapy.
