What is an Enlarged Prostate?

Benign Prostatic Hyperplasia, or simply BPH, is a non-cancerous, enlargement of the prostate gland. It is a common condition among aging men. The prostate gland, located under the bladder, surrounds the urethra. It is responsible for reproductive functions as it produces seminal fluid which nourishes and transports sperms. Its location around the urethra means enlargement can impact urination. 

It is situated right under the bladder surrounding the urethra and may grow larger with age. 

However, if it gets too big, it can pinch the urethra, causing it to narrow, resulting in unpleasant urinary problems. In severe cases of BPH, patients may experience urinary discomfort, frequent urination, and interrupted sleep, affecting their routine life. 

Primary Causes of Enlarged Prostate

Knowing the causes behind an enlarged prostate can help in effective management and treatment. We’ll explore the primary factors contributing to this common condition among men:

1. Age-Related Changes

As men get older, it's normal for the prostate gland to grow. Benign Prostatic Hyperplasia (BPH) primarily affects men over the age of 50. By the time men reach their 60s, and beyond, they can have some degree of prostate enlargement. 

2. Hormonal Imbalance

As men age, the levels of active testosterone decrease, which can affect prostate size. One especially influential hormone is Dihydrotestosterone (DHT). High levels of DHT can contribute to the growth of the prostate. This hormone is a byproduct of testosterone, transformed by an enzyme located in the prostate gland itself. 

3. Genetics

Genetics play a significant role in determining the likelihood of developing BPH. If it runs in your family and especially if direct members suffer from some prostate health problems, then you stand a higher chance of acquiring this condition. 

The combination of ageing, hormonal changes, and genetics - increase the risk of BPH. Recognising these causes is the first step in proactive health management, allowing for earlier detection and more effective enlarged prostate treatment strategies. 

Additional Factors That Can Lead to an Enlarged Prostate

Other elements also can cause an enlarged prostate, for example:

Lifestyle Factors

Like many other chronic conditions, sedentary lifestyle is also a risk factor for BPH. Physical inactivity can lead to a series of poor health outcomes and affects prostate health as well. Thus, regular workouts and diet control are mandatory in countering prostate disorders.

Chronic Medical Conditions

Chronic lifestyle conditions such as diabetes often cause hormonal disturbances, cause inflammation and bladder dysfunction, ultimately aggravating BPH. Therefore, proper medication for your health concerns and physical exercise supports the general well-being of an individual and also reduces the risk or severity of an enlarged prostate.

Complications from Untreated Enlarged Prostate

Leaving an enlarged prostate untreated can lead to several serious urinary complications, impacting overall health.

  • BPH can cause acute urinary retention, a painful condition requiring immediate intervention. Chronic retention, if untreated, can lead to permanent bladder damage and increased risk of infections
  • Over time, chronic retention can also cause the bladder to stretch and weaken, reducing its ability to empty and increasing the risk of urinary tract infections (UTIs).
  • Incomplete bladder emptying can also lead to the formation of bladder stones. These hard masses can cause further irritation, bleeding, and blockage of urine flow.
  • The pressure from trying to pass urine through a constricted urethra may also force urine back into the kidneys. This condition is known as vesicoureteral reflux and can lead to kidney damage and infections. In severe cases, prolonged obstruction might even result in kidney failure.

Thus, recognising the symptoms early and seeking appropriate treatment can prevent these complications. Regular medical check-ups and monitoring are vital for managing prostate health and mitigating the risks associated with an untreated enlarged prostate.
