Medical review of my father suffering from prostate enlargement

My father has been suffering from enlarged prostate for quite a long time due to nocturia and frequent urination.
I have been taking saw palmetto, which I was recommended by home shopping channels and acquaintances, for quite a long time.
I don't feel much better, and I only take medication when I do, so I visit the hospital.


I have heard that quite a few middle-aged and elderly men suffer from prostate enlargement issues.
A few years ago, my father also mentioned these symptoms, so I recommended he see a doctor, but perhaps he didn't feel it was necessary because it was early-stage prostate enlargement.
It seemed like you were just staying as you were.
This symptom is strangely less troublesome during the day. However, at night or early morning, I suffer from frequent urination. Additionally, the feeling of residual urine is strong, so it's not refreshing, and it doesn't stop after just one or two times.
Unable to endure, I heard that a health supplement recommended by those around me for prostate enlargement is a medication from the saw palmetto family.
So, you tried several different types alternately, but it seems you didn't see much of an effect.
So, I went to a somewhat larger hospital for treatment.
The diagnosis was benign prostatic hyperplasia.
I heard that symptoms like residual urination and frequent urination are all among the symptoms of this prostate enlargement.
So, we decided to proceed with medication treatment first.
You have been taking hospital medication for benign prostatic hyperplasia for a few weeks, and while there has been some effect, it doesn't seem to be very satisfactory.

What are some prevention methods or effective treatments for prostate enlargement that you are aware of?
