Sometimes gynecomastia is a symptom of diseases of internal organs, endocrine glands.For example, gynecomastia can accompany chronic renal failure, hyperthyroidism (increased thyroid function), hyperprolactinemia (increased prolactin levels as a result of pituitary disease), malnutrition, starvation, cirrhosis, obesity (available aromatase enzyme in fat tissue, which promotes the conversion of testosterone into estrogen).

Gynecomastia can also be a side effect of certain drugs:

- Spironolactone (Veroshpiron) - a diuretic, which has anti-androgen activity;
- Calcium channel blockers - used to treat hypertension, ischemic heart disease (nifedipine, amlodipine, verapamil);
- Angiotensin converting enzyme inhibitors - drugs for the treatment of hypertension and congestive heart failure (captopril (Capoten), enalapril (Enap, ednit), lisinopril (Diroton);
- some antibiotics and antifungal drugs (isoniazid, ketoconazole (Nizoral), metronidazole (Trichopolum, Metrid);
- anti-ulcer drug (ranitidine (Zantac), cimetidine, omeprazole (Omez);
- hormonal treatments for prostate cancer;
- methyldopa (dopegit) - antihypertensive drug;
- antiretroviral therapy for HIV infection;
- digoxin - a cardiac glycoside, appointed in heart failure;
- diazepam (Relanium Seduxen) - tranquillizer;

diagnosis of gynecomastia

preliminary diagnosis is made by palpation (palpation) of breast tissue, the axillary lymph nodes.

uses ultrasound breast, axillary lymph nodes, less mammography and breast biopsy to confirm the diagnosis, detection of breast cancer.

Laboratory studies should include a definition of levels of testosterone, estradiol, luteinizing hormone (LH), thyroid stimulating hormone (TSH), prolactin, and human chorionic gonadotropin (hCG).With increasing levels of estradiol and hCG studies to exclude malignancy should be implemented immediately!

If necessary, appoint men as ultrasound of the testes, adrenal computed tomography to rule out a tumor.

often need help therapist, endocrinologist, urologist, oncologist surgeon, neurologist.
