What Is Gynecomastia?

 Gynecomastia Is Overdevelopment Of The Male Breast.

In response to too much estrogen (a female hormone) or too little testosterone (a male hormone), the glandular tissue of the breast swells and forms a breast bud (enlarged breast).


What Are The Symptoms Of Gynecomastia?


Women and young men with gynecomastia may also experience rubbery or firm breasts in addition to enlarged breasts. On one or both sides of the breast, boys may have a breast bud about the size of a nickel or quarter. Adolescent boys often develop breast buds during puberty. Usually, they go away within the first year, but may last for up to two years.


What Causes Gynecomastia?


In newborns, gynecomastia is caused by estrogen from the mother. Breast buds are common in baby boys. Breast buds tend to go away gradually by 6 months of age, but they can last longer in some babies.


In preteen boys, breast buds are common during puberty. The buds may last up to 2 years, but they tend to go away within the first year. Gynecomastia can also be caused by an estrogen-producing tumor.


In teen boys, gynecomastia is caused by the hormonal changes of puberty. Gynecomastia occurs in many boys during early puberty to middle puberty. It usually goes away within 6 months to 2 years.


Most adult males with gynecomastia suffer from another condition, such as liver or lung cancer, cirrhosis of the liver, excessive thyroid activity, or hormone disorders, such as cancer of the pituitary gland, adrenal glands, or testicles.


It is also possible to develop gynecomastia after using alcohol, marijuana, methamphetamine, and heroin. A change in hormone levels can lead to gynecomastia in older males.


Use of certain medicines may also cause gynecomastia, including:


~Steroids, such as prednisone or dexamethasone.

~Medicines used to treat ulcers (such as cimetidine).

~Medicines used to treat epilepsy (such as phenytoin [Dilantin]).

~Digitalis and other heart medicines.

Chemotherapy drugs, especially alkylating agents, a family of anticancer drugs that interfere with cell DNA and inhibit cancer cell growth

~Antiandrogen drugs (such as flutamide, cyproterone, and spironolactone).

~Antianxiety and antidepressant medicines (such as diazepam [Valium] and tricyclic antidepressants).



How Is Gynecomastia Diagnosed?


A physical exam and medical history are usually sufficient to diagnose gynecomastia. There is usually no need for tests in most cases. To exclude other problems, a biopsy may be necessary if the breast lump is unusually large, one-sided, tender, hard, or fixed.


The doctor should be notified if any of his close relatives (mother, sister, or daughter) suffer from breast cancer. A biopsy or surgery can be used to determine whether a lump is cancerous.


How Is Gynecomastia Treated?


Gynecomastia in babies and teens normally does not require treatment and will usually go away on its own. If it is caused by medicine or disease, stopping the medicine or treating the disease will often cure the gynecomastia.


  If it is caused by a lack of testosterone and increase in estrogen, hormonal treatment may be prescribed. Surgery may be a choice for some men if other treatments have not worked.

The Ketogenic Diet: Benefits, Risks, and How to Do It Safely

  *A plain-language guide to one of the world's most talked-about diets* What Is the Ketogenic Diet? Imagine your body as a car that normally runs on gasoline, that gasoline is carbohydrates (carbs), the sugars and starches found in bread, rice, fruit, and pasta. The ketogenic diet, or "keto," swaps that fuel source entirely. By eating very few carbs, usually less than 50 grams a day (about the amount in one medium banana), and replacing them with high-fat foods, you push your body into a metabolic state called **ketosis**. In ketosis, your liver breaks down fat into molecules called *ketones*, which your brain and muscles use as an alternative energy source. In simple terms: instead of burning sugar, your body burns fat. That's the entire premise of keto, and it's why millions of people around the world try it every year. A standard keto diet looks something like this: - **70% of calories from fat** (avocados, olive oil, nuts, fatty fish, cheese) - **25% from pro...
