Abdominal Pain in Adults

Abdominal pain in adults can range from a mild stomach ache to severe pain. Examples of causes of abdominal pain in adults include appendicitis, gallbladder disease, gastric ulcers, pancreatitis, heart attack, kidney stones, diverticulitis, shingles, spider bites, and more. Information about when to seek medical care for abdominal pain is also provided.
Amenorrhea

Amenorrhea, the absence of menstrual bleeding, can be either primary or secondary. Causes of amenorrhea include problems with the hypothalamic organs, problems with the pituitary organs, problems with the ovarian glands and organs, or functional causes (bulimia, anorexia, depression, etc.) Treatment for amenorrhea is generally directed toward the condition that is causing amenorrhea.
Aortic Aneurysm

An aortic aneurysm is a medical emergency. Abnormal enlargement or bulging of the aorta becomes an aortic aneurysm when this area becomes weakened. Some of the symptoms of an aortic aneurysm include back pain, chest pain, dizziness, sweating, nausea, and vomiting. Common causes of an aortic aneurysm include heart disease, high blood pressure, diabetes, inflammatory aneurysm, or injury to the chest wall. Treatment of aortic aneurysm depends upon the cause.
Appendicitis

The cause of appendicitis is not clear. Common symptoms of appendicitis include vague abdominal pain, nausea, vomiting, fever, constipation, diarrhea. Some people have no symptoms of appendicitis. Treatment for appendicitis is generally an appendectomy (removal of the appendix).
Blood Clots

Blood is supposed to clot to help repair a blood vessel that is injured. Clots or thrombi become a problem when they form inappropriately. There are a variety of illnesses and risk factors that can lead to blood clot formation such as atrial fibrillation, heart attack, strokes, transient ischemic attacks (TIAs), pulmonary embolism, deep vein thrombosis (DVT), and more. Diagnosis and treatment of blood clots depends on the cause and severity of the clot.

Arrhythmias or heart rhythm disorders are conditions that causes changes in the normal heartbeat. There are numerous types of arrhythmias, for example, supraventricular tachycardia, sinus sick syndrome, atrial fibrillation, atrial flutter, and ventricular fibrillation. Signs and symptoms of an arrhythmia may include: Chest pain or discomfort Shortness of breath Palpitations Racing heart sensation Treatment for arrhythmias depend upon the cause.
Ascites

Ascites is an accumulation of fluid in the peritoneal cavity (abdominal cavity). The primary cause of ascites is liver disease such as; cirrhosis, acute liver failure (Tylenol, acetaminophen overdose), Budd-Chiari syndrome, and cancer. Other causes of ascites include congestive heart failure, nephrotic syndrome, pancreatic disorders, diseases of the ovary, hypothyroidism, and direct irritation of the peritoneum. Symptoms of ascites include abdominal pain, shortness of breath, easy bruising, and edema (swelling). Treatment for ascites depends on the cause.

Symptoms and signs include red, raised, scaly areas on the skin that may itch or burn. Treatment may involve topical therapy, phototherapy, and medication.
Sprains and Strains

An injury to a ligament is called a sprain, while an injury to a muscle or tendon is called a strain. Symptoms and signs include pain, swelling, bruising, and decreased range of motion. Rest, ice, compression, and elevation of the injury is the standard treatment for sprains and strains.
Abdominal Pain in Children

Abdominal pain in children can range from trivial to life-threatening. Symptoms of abdominal pain range from vomiting, diarrhea, fever, groin pain, urinary problems, or skin rash. The location of the abdominal pain may be around the belly button, occurs only at night, while eating. The pain pain also may be intermittent. Treatment of abdominal pain in children is depends on the cause. Possible causes of abdominal pain in children include infections, food related (food allergy or food poisoning), poisoning from medication, food, household products, appendicitis, diabetes, or spider bites.
Testicle Infection (Epididymitis)

Epididymitis is inflammation or infection of the epididymis that is usually caused by a bacterial infection. Two main groups of organisms are responsible for most cases of epididymitis; STD organisms and coliforms. Symptoms of epididymitis include abdominal pain, scrotal pain, scrotal swelling, painful urination, blood in the urine, urethral discharge, fever, chills, and nausea. Treatment is with antibiotics.
Testicular Pain

If you are a male, we don't need to describe what "testicular swelling, discomfort, or pain" feels like to you. And hopefully those around you can sympathetically understand the pain you're in. Medically speaking, testicular or scrotum pain is defined as a discomfort or pain in the testicles or scrotum. The pain can range from mild - to severe and serious as in testicular torsion - which is a surgical emergency.Causes of the pain range from common to less common; examples include trauma, epididymitis (testicle infection), kidney stones, testicular torsion (a surgical emergency), STDs (sexually transmitted diseases), enlarged prostate (BPH), inguinal hernia, orchitis (an inflammatory condition in one or both testicles caused by infections), cancer, kidney stones, abscesses, gangrene infections, vasculitis of the wall of the scrotum (henoch-schonlein purpura, HSP), testicular tumor with infection or hemorrhage, and varicocele. A doctor or other health-care professional can help diagnose the cause of your pain by performing a physical exam and ordering laboratory tests. Treatment of testicular or scrotal pain depends on the cause. In some cases, for example in kidney stones, the pain is resolved once the stones are removed. The prognosis depends upon the cause.
Testicular Torsion

Testicular torsion is a painful condition caused by the twisting of the spermatic cord, which causes a loss of blood flow to the testicle. It is a surgical emergency that may result in the loss of the testicle. The main cause is an anatomical abnormality called the bell clapper deformity. Symptoms include testicular pain, sudden swelling, nausea, vomiting, abdominal pain, or fever. Treatment for testicular torsion is surgery.

Thyroid Nodules

Thyroid nodules are lumps that are either solid or fluid-filled. Thyroid nodules may be benign or malignant (cancerous). Thyroid nodules may be caused by goiters, Hashimoto's thyroiditis, thyroid cysts, benign thyroid tumors, malignant thyroid tumors, or thyroid cancer. Treatment depends upon the type and cause of the thyroid nodule.
Thyroid Problems

Diseases of the thyroid gland can lead to hyperthyroidism, hypothyroidism, thyroid nodules, thyroid goiters, or thyroid cancer. Symptoms of both hypo- and hyperthyroidism-related conditions include constipation, fatigue, weight gain, cold or heat intolerance, to coma. Treatment depends upon the thyroid condition.
Urethritis in Men

Urethritis, inflammation of the urethra, may cause symptoms and signs that include discharge, burning, pain, urinary urgency, itching, and blood in the urine. Treatment involves antibiotics, sitz baths, drinking plenty of fluids, and taking nonsteroidal anti-inflammatory medications.
Incontinence

Urinary incontinence is when there's an involuntary loss of urine. There are many types of incontinence, including urge incontinence (overactive bladder), mixed incontinence, reflex incontinence, and stress incontinence. Potential causes of incontinence include overactive bladder muscles, weak bladder muscles, blockage of urine flow, and nerve damage. Treatment may involve dietary changes and exercise, including Kegel exercises and using vaginal weights.
Uterine Fibroids

Uterine fibroids are benign tumors (non-cancerous tumors) of a woman's uterus. The exact reason why some women develop uterine fibroids is not known. Obesity, nulliparity, and early menstruation are conditions associated with uterine fibroids. Some of the symptoms of uterine fibroids include irregular vaginal bleeding, constipation, lower abdominal pain, infertility, and more.
