What causes the prostate to enlarge?

Although the exact trigger of BPH (Benign Prostatic Hyperplasia) is not fully known and may vary from one man to another, there are risk factors that contribute to the condition. Benign prostate enlargement means your prostate grows in size without being cancerous. As the prostate swells and becomes bigger, it presses on your urethra and bladder and may cause a number of urinary and bladder function problems. The known contributing factors to prostate enlargement are age, hormones, stress levels and diet.

1. Age

Your age is a risk factor and not a cause of BPH. Prostate growth is considered a normal part of aging. In fact, the prostate usually goes through two major periods of growth as a man ages. During early puberty, the prostate doubles in size. Then from the age of 25 the gland enters a second phase of growth and continues to increase in size for the rest of his life. It’s typically during this second growth phase that benign prostatic hyperplasia occurs. About 50 percent of men over the age of 50 have BPH, while up to 90 percent of men over 80 years old have the condition.

2. Hormones

Hormones have a major role in triggering BPH. For instance, testosterone — the male sex hormone responsible for sexual development, muscle mass, deep male voice and libido — is converted to DHT (dihydrotestosterone) when it is in excess in the body. DHT is a useful hormone in adolescents because it ensures normal growth and development of sexual organs, including the prostate. But the production of excess quantities of DHT results in problems such as aggression and acne in adolescents. In older men, excess production of DHT causes the prostate to continue to grow and enlarge. If left unchecked, this could lead to an enlarged prostate and other problems associated with the gland.

3. Diet

Prostate enlargement is a more common problem in Western countries such as the U.S. and UK, but occurs in lower rates in Asian countries like Singapore and Japan because of dietary reasons. A typical Western diet contains simple carbohydrates, refined sugar, meat, dairy and unhealthy fats, while traditional Asian and Eastern diets are often richer in complex carbohydrates, vegetables and healthy soya-based proteins. The dietary differences are therefore critical for the varied incidences of BPH in the Western and Eastern countries.

The regular consumption of red meat escalates the risk of developing BPH by 38 percent, and regular dairy intake not only contributes to joint pain and hay fever through inflammation, but also inflames the prostate and accelerates the enlargement process. On the other hand, consuming 4 or more vegetable servings a day decreases the risk of BPH by 32 percent, and regular intake of soya reduces the chances of having an enlarged prostate. Likewise, zinc, commonly found in seeds and nuts and often missing in typical Western diets, is critical for a healthy prostate.

Poor diets lacking in fiber can cause constipation, which badly affects the prostate. The prostate is located very close to the bowels. If toxins remain in the bowels for a long time they start to leak into the surrounding tissues and into the prostate. When that happens, inflammation and pain may occur in the prostate. Similarly, the pressure caused by constipated bowels on both the bladder and prostate can worsen BPH symptoms.

4. Stress levels

Prolonged repeated exposure to stress, such as men who have high-pressure jobs, who commute frequently or who are rarely relaxed, can lead to or worsen BPH. For men already suffering the symptoms of an enlarged prostate, stress leads to inflammation of the prostate and worsens the symptoms. It also causes muscular tension, which results in further restriction of bladder function. Increased exposure to stress quickly depletes the body of nutrients and one of the most frequently stress exhausted nutrients is zinc, which is vital for prostate health. Repeated high stress levels also lead to increased secretion of testosterone and DHT hormones, which contribute to the growth of the prostate.

So what’s your role in preventing BPH?

You can’t do anything about your age, but you can do something about your lifestyle and diet to boost the health of your prostate. Start by avoiding or cutting down on dairy and meat, add lots of vegetables, fruits, nuts, seeds and whole grains to your nutrition regimen, and try including soya products like miso, tofu and tempeh in your diet. Initially that may be difficult if you are used to consuming meat and dairy-heavy meals. But by incorporating tasty, plant-based substitutes such as tofu, three-bean curry, mushroom risotto and vegetable satay, you can quickly get used to meals without meat and dairy. Take steps to reduce your stress levels by dealing with the underlying causes of your stress. Take a stress remedy, practice mindfulness or see a counselor — whatever works best for you.
