Eye, Painful Red: From 1 Different Sources

A common combination of eye symptoms that may be due to any of several eye disorders.

Uveitis is a common cause of dull, aching pain. The redness is caused by widening of blood vessels around the iris. Another serious cause of pain and redness in one eye is acute closedangle glaucoma. Other causes include keratitis, usually due to a corneal ulcer, or a foreign body in the eye (see eye, foreign body in). The most common cause of redness and irritation in the eye is conjunctivitis.

Intercourse, Painful

Pain during sexual intercourse, known medically as dyspareunia, which can affect both men and women. Pain may be superficial (around the external genitals) or deep (within the pelvis).

In men, superficial pain may be due to anatomical abnormalities such as chordee (bowed erection) or phimosis (tight foreskin). Prostatitis may cause a widespread pelvic ache, a burning sensation in the penis, or pain on ejaculation.

Scarring (after childbirth, for example) and lack of vaginal lubrication, especially after the menopause, may cause painful intercourse in women. Psychosexual dysfunction may also cause pain during intercourse. Vaginismus, a condition in which the muscles of the vagina go into spasm, is usually psychological in origin. Deep pain is frequently caused by pelvic disorders (such as fibroids, endometriosis, ectopic pregnancy, or pelvic inflammatory disease due to sexually transmitted infections), disorders of the ovary (such as ovarian cysts), and disorders of the cervix. Other causes are cystitis and urinary tract infections.Treatment is directed at the underlying cause of the pain.

If the discomfort is psychological in origin, special counselling may be needed (see sex therapy).... intercourse, painful

Painful Arc Syndrome

Urination, Painful

Pain or discomfort that occurs when urine is being passed. Painful urination is known medically as dysuria. The pain is often described as burning; sometimes it is preceded by difficulty in starting urine flow. Pain after the flow has ceased, with a strong desire to continue, is called strangury.

The most common cause, especially in women, is cystitis. Other causes include a bladder tumour, bladder stone (see calculus, urinary tract), urethritis, balanitis, prostatitis, vaginal candidiasis (thrush), or allergy to vaginal deodorants. Strangury is usually caused by spasm of an inflamed bladder wall, but it may be due to bladder stones. Mild discomfort when passing urine may be caused by highly concentrated urine.

Dysuria may be investigated by physical examination, urinalysis, urography, or cystoscopy. (See also urethral syndrome, acute.)... urination, painful

Weight Reduction

The process of losing excess body fat. A person who is severely overweight (see obesity) is more at risk of various illnesses, such as diabetes mellitus, hypertension (high blood pressure), and heart disease.

The most efficient way to lose weight is to eat 500–1,000 kcal (2,100–4,200 kJ) a day less than the body’s total energy requirements. Exercise also forms an extremely important part of a reducing regime, burning excess energy and improving muscle tone.

In most circumstances, drugs play little part in a weight loss programme.

However, sibutramine and orlistat may be useful adjuncts to a reducing diet and may be appropriate for some people with a high (see body mass index). Appetite suppressants related to amfetamines are not recommended.... weight reduction
