Overview
Alopecia Areata
Alopecia areata is an autoimmune condition that causes the immune system to attack hair follicles, resulting in hair loss. It commonly produces one or more smooth, round patches of hair loss on the scalp or other areas of the body, although more extensive forms can affect much of the scalp or all body hair. Hair may regrow spontaneously, but the course is unpredictable and repeated episodes can occur. Changes to the nails may accompany more extensive disease.
Benign Prostatic Hyperplasia
Benign prostatic hyperplasia is a noncancerous enlargement of the prostate gland that becomes more common with aging. An enlarged prostate can press on the urethra and interfere with the normal flow of urine. Symptoms may include difficulty starting urination, a weak or interrupted stream, frequent or urgent urination, nighttime urination, and a feeling that the bladder has not emptied completely.

Diagnosis
Alopecia Areata
Alopecia areata is generally diagnosed through examination of the pattern of hair loss and the scalp, together with medical and family history. Dermoscopy can reveal characteristic changes in affected follicles. A scalp biopsy may be considered when the diagnosis is uncertain. Blood tests can be useful when there are signs of associated autoimmune, thyroid, nutritional, or other conditions. The clinician also considers other causes of patchy hair loss, including fungal infection and scarring disorders.
Benign Prostatic Hyperplasia
Diagnosis is based on urinary symptoms, medical history, and physical examination, including a digital rectal examination when appropriate. Urinalysis can help exclude infection or other causes of urinary symptoms. Depending on the situation, tests may include prostate-specific antigen measurement, urinary flow testing, measurement of urine remaining after urination, or imaging of the prostate and urinary tract.
Prevention
Alopecia Areata
There is no proven way to prevent alopecia areata because its autoimmune triggers are not fully understood. Maintaining general health and managing associated autoimmune conditions can support overall well-being but cannot guarantee prevention. People with sudden patchy hair loss should seek evaluation because some causes are treatable and early diagnosis can guide management. Avoiding unnecessary scalp trauma or harsh hair treatments can reduce additional hair damage, although these practices do not prevent the autoimmune process.
Benign Prostatic Hyperplasia
There is no guaranteed way to prevent benign prostatic hyperplasia because prostate enlargement is strongly related to aging. Maintaining a healthy weight, exercising regularly, managing diabetes and cardiovascular risk factors, and limiting excessive fluid intake before bedtime may help reduce urinary symptoms. People with persistent or worsening urinary symptoms should be evaluated so that other causes can be excluded and appropriate treatment considered.
Risk Factors
Alopecia Areata
Risk factors for alopecia areata include a family history of the condition and a personal or family history of autoimmune disease. It can occur at any age but often begins earlier in life. Certain immune-related conditions may increase susceptibility. The presence of a risk factor does not predict how extensive hair loss will become. Some people develop alopecia areata without any known risk factor.
Benign Prostatic Hyperplasia
The main risk factor for benign prostatic hyperplasia is increasing age. A family history of the condition may increase susceptibility. Metabolic conditions such as obesity and diabetes have been associated with urinary symptoms and prostate enlargement. Cardiovascular disease and physical inactivity may also be associated with increased risk. Symptoms generally become more common as men grow older.
