Abdominal pain can reflect a major problem with one of the organs in the abdomen such as the appendix, gallbladder, large and small intestine, pancreas, liver, colon, duodenum, and spleen.
    • Low Blood Pressure
      • Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include light-headedness, dizziness, or even fainting if not enough blood is getting to the brain. Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.
    • Kidney Stones
      • One in every 20 people develop a kidney stone at some point in their life. A kidney stone is a hard mineral and crystalline material formed within the kidney or urinary tract. Kidney stones symptoms and signs are, blood in the urine and pain in the abdomen, flank (lower back), or groin. A number of different conditions can lead to kidney stones including: gout, hypercalciuria, people with inflammatory bowel disease, kidney disease, and hypoparathyroidism. Some medications also increase the risk of kidney stones.
    • Appendicitis
      • Appendicitis is an inflammation of the appendix. Appendicitis often causes fever, loss of appetite, and right lower quadrant abdominal pain. Delay in surgery can result in appendix rupture with potentially serious complications.
    • Sciatica
      • Sciatica pain, caused by irritation of the sciatic nerve, typically radiates from the low back to behind the thigh to below the knee. Disc herniation is usually the cause of sciatica. Medication to alleviate pain, physical therapy, and bed rest are treatments for sciatica.
    • Lung Cancer
      • Lung cancer kills more men and women than any other form of cancer. Eight out of 10 lung cancers are due to tobacco smoke. Lung cancers are classified as either small cell or non-small cell cancers.
    • Lower Back Pain
      • There are many causes of back pain. Pain in the low back can relate to the bony lumbar spine, discs between the vertebrae, ligaments around the spine and discs, spinal cord and nerves, muscles of the low back, internal organs of the pelvis and abdomen, and the skin covering the lumbar area.
    • Pinched Nerve
      • A pinched nerve can be caused of a variety of conditions, for example, carpal tunnel syndrome, herniated disc, sciatica, arthritis, spinal stenosis, trauma, and more. Common symptoms of a pinched nerve include pain, numbness, tingling, and weakness. Treatment of a pinched nerve depends on the cause of the pinched nerve.
    • Intestinal Gas
      • Gas or "intestinal gas" means different things to different people. Everyone has gas and eliminates it by belching or farting (passing it through the rectum).
    • Sinus Infection
      • Sinus infection (sinusitis) signs and symptoms include headache, fever, and facial tenderness, pressure, or pain. Treatments of sinus infections are generally with antibiotics and at times, home remedies.
    • Diverticulitis (Diverticulosis)
      • Diverticulitis is a condition in which diverticuli in the colon rupture. The rupture results in infection in the tissues that surround the colon. Diverticulitis symptoms include: abdominal pain, abdominal cramps, diarrhea, constipation, and bloating. Treatment methods include prescription medications, and in some cases, diverticulitis surgery.
    • Kidney Infection
      • Kidney infection (pyelonephritis) usually is caused from bacteria that have spread from the bladder from a UTI (urinary tract infection), poor hygiene, sexual intercourse, pregnancy, catheter, cystoscope exam, surgery, kidney stones, or prostate enlargement. Symptoms of kidney infection include: back pain, frequent urination, pain during urination, fever, and or pus or blood in the urine. Kidney infection is usually treated with antibiotics.
    • Brain Tumor
      • A brain tumor can be either benign (non cancerous) or malignant (cancerous), primary, or secondary. Causes and risk factors include age, gender, family history, and exposure to chemicals.

Patients with associated cirrhosis caused by chronic hepatitis B or C infections, alcohol, and hemochromatosis are at the greatest risk of developing liver cancer. Many patients with liver cancer do not develop symptoms until the advanced stages of the tumor which usually makes prognosis poor. The combination of an imaging study (ultrasound, CT, or MRI scans) and an elevated blood level of alpha-fetoprotein will most effectively diagnose liver cancer, while a liver biopsy can make a definitive diagnosis. Medical treatments, including chemotherapy, chemoembolization, ablation, and proton beam therapy, are not very effective. Surgical removal of the tumor or a liver transplant may be most effective in certain cases.
    • Blood Clots
      • Blood clots can occur in the venous and arterial vascular system. Blood clots can form in the heart, legs, arteries, veins, bladder, urinary tract and uterus.

Some blood clots are a medical emergency. Blood clots are treated depending upon the cause of the clot. Blood clots can be prevented by lowering the risk factors for developing blood clots.
