BHP in a medical context is almost always a typo for BPH, which stands for benign prostatic hyperplasia, commonly known as an enlarged prostate. It’s a noncancerous condition in which the prostate gland gradually grows larger, squeezing the urethra and making it harder to urinate. BPH is extremely common in men over 50 and becomes more prevalent with each decade of life.
Less commonly, BHP can refer to the Basic Health Program, a state-run health coverage option under the Affordable Care Act. Both meanings are covered below.
BPH: Enlarged Prostate Explained
The prostate is a walnut-sized gland that sits just below the bladder and wraps around the urethra, the tube that carries urine out of the body. In BPH, cells in the inner zone of the prostate multiply, and the gland slowly expands. This expansion compresses the urethra from the outside and can partially block the bladder’s outlet. Over time, the bladder has to work harder to push urine through the narrowed passage, and that extra effort can eventually weaken the bladder muscle itself.
Two things drive the obstruction. The first is the physical bulk of the enlarged tissue pressing on the urethra. The second is muscle tension: smooth muscle fibers inside the prostate can tighten and further restrict flow. This is why prostate size alone doesn’t always predict how severe symptoms will be. A moderately enlarged prostate with a lot of muscle tension can cause worse problems than a much larger one with less tension.
Common Symptoms
BPH symptoms fall into two broad categories. Storage symptoms affect how your bladder holds urine, while voiding symptoms affect how urine comes out.
- Storage symptoms: needing to urinate frequently (especially at night), sudden urgent need to go, and occasional leaking before you reach the bathroom.
- Voiding symptoms: a weak or intermittent stream, difficulty starting urination (hesitancy), straining, and the feeling that your bladder hasn’t fully emptied.
Symptoms typically develop gradually. Many men initially notice they’re getting up once or twice a night to urinate, then realize their stream has weakened over the course of months or years. Because the change is slow, it’s common to dismiss early symptoms as normal aging.
How BPH Is Diagnosed
A doctor will usually start with a digital rectal exam, inserting a gloved finger into the rectum to feel the size and shape of the prostate. This takes seconds and gives a rough sense of enlargement. A urine test checks for infection or blood that could explain similar symptoms, and a blood test screens for kidney problems that can result from long-standing obstruction.
A PSA (prostate-specific antigen) blood test is often part of the workup. PSA levels tend to rise when the prostate is enlarged, but they can also rise after infections, recent procedures, or due to prostate cancer. An elevated PSA doesn’t mean cancer, but it may prompt further evaluation. Some men are also asked to keep a 24-hour voiding diary, recording how often and how much they urinate, which helps quantify the problem.
If the picture is unclear, additional tests like a transrectal ultrasound to measure prostate size, urodynamic studies to assess bladder pressure, or a prostate biopsy may follow.
Medication Options
Two main classes of drugs treat BPH, and they work in different ways.
The first class relaxes the smooth muscle inside the prostate and bladder neck, reducing that dynamic component of obstruction. These medications (alpha-blockers, such as tamsulosin) provide relatively quick symptom relief, often within days to a couple of weeks. They don’t shrink the prostate, but they make it easier for urine to flow through.
The second class actually shrinks the gland by blocking the conversion of testosterone into a more potent hormone that drives prostate growth. These drugs take longer to work. Most of the size reduction happens over about six months, and it can take up to a year for the full effect. They’re typically prescribed for men with noticeably enlarged prostates.
Some men take both types together, combining the quick relief of muscle relaxation with the long-term benefit of volume reduction. Recent guidelines also recognize combination therapy with a daily low-dose erectile dysfunction medication alongside either drug class, which can help with both urinary symptoms and sexual function.
For men whose main complaint is frequent, urgent bathroom trips rather than a weak stream, a different category of medication that calms overactive bladder contractions may be added.
Procedures for Moderate to Severe BPH
When medications aren’t enough, or when side effects are bothersome, several procedures can physically open up the blocked channel.
The traditional surgical option, TURP (transurethral resection of the prostate), involves inserting an instrument through the urethra and cutting away excess prostate tissue. It’s highly effective but carries risks of urinary incontinence, retrograde ejaculation (where semen goes into the bladder during orgasm instead of out), and sexual dysfunction. It also requires general or spinal anesthesia and a hospital stay.
Newer minimally invasive options have shifted the landscape considerably. Water vapor therapy (Rezum) delivers steam through the urethra into the enlarged tissue, causing it to break down and be reabsorbed over several weeks. The UroLift system takes a different approach: small implants are placed to hold the prostate lobes apart, like curtain tiebacks, opening the urethra mechanically without destroying tissue. Both can often be done in an office setting under local anesthesia or light sedation, with faster recovery and a better chance of preserving ejaculatory function compared to TURP.
Laser-based procedures, including holmium laser enucleation, can treat prostates of virtually any size and are recommended when the gland is very large. Prostate artery embolization, performed by an interventional radiologist, is a newer option that shrinks the gland by cutting off part of its blood supply.
What Happens if BPH Goes Untreated
BPH isn’t cancer and doesn’t turn into cancer, but ignoring it for years can lead to real complications. The most immediate risk is urinary retention, either acute (a sudden, painful inability to urinate that requires emergency catheterization) or chronic (the bladder never fully empties, leaving a growing pool of stagnant urine).
That stagnant urine creates a breeding ground for recurrent urinary tract infections. Minerals in the urine can also crystallize into bladder stones, which cause pain, blood in the urine, and further obstruction. Over time, the bladder wall thickens and loses its ability to contract normally.
The most serious long-term risk is kidney damage. When the bladder can’t empty properly, pressure backs up through the ureters and into the kidneys, causing them to swell (hydronephrosis). Chronic high-pressure retention, combined with recurrent infections, can lead to permanent kidney dysfunction. Bladder stones and recurrent UTIs are themselves predictors of declining kidney function in men with BPH.
BHP as Basic Health Program
In a non-prostate context, BHP sometimes refers to the Basic Health Program created under Section 1331 of the Affordable Care Act. This is a state-run health coverage option for low-income residents whose income falls between 133% and 200% of the federal poverty level, too high for Medicaid but low enough to need help affording insurance. Lawfully present noncitizens who don’t qualify for Medicaid due to immigration status are also eligible if their income is under 133% of the poverty level.
Only a handful of states have implemented a BHP. Minnesota has offered one since January 2015. New York ran its program from April 2015 but suspended it in April 2024. Oregon received federal approval in June 2024 and launched its program in July of that year. If you’re searching “BHP medical” in the context of health insurance, you’re likely in one of these states and looking at coverage options through your state’s program rather than the federal marketplace.
