Does Coffee Enlarge The Prostate? (Truth Revealed)

Coffee and caffeine can be good for your prostate health

Coffee is the most widely loved drink that serves both as an energy booster and a quick refreshment. No matter whether you’re pulling an all-nighter or ready to hit the gym, the drink has been a constant companion for millions of people worldwide.

Many studies have found the association of several health benefits with the regular consumption of coffee.

Amidst the benefits, there have been growing concerns as well on the cardiovascular, prostate, and nervous health of the body due to caffeine’s stimulating and diuretic effects.

Short answer: Coffee itself won’t enlarge the prostate. However, the caffeine present in the drink may trigger the symptoms of Benign Prostatic Hyperplasia due to its diuretic effects on the bladder and prostate.

In the following sections, I’ll be giving a broader explanation of the related queries so let’s get started!

What is Benign Prostatic Hyperplasia?

Benign prostatic hyperplasia (BPH) is a common medical condition in elderly men that is caused by the enlargement of the prostate.

The prostate is a part of the male reproductive system that is walnut-sized. It is made of glandular, muscular tissues and is responsible for producing seminal fluid.

BPH is the condition in which this prostate becomes larger in size. This is a very common phenomenon in men as they grow older. Reports show that by the age of 60, about 50% of the men may have signs of BPH and by the age of 85, about 90% will have the signs.

Though the condition is noncancerous, still some of the symptoms of BPH are similar to prostate cancer. This calls for men to take a proper screening of their body especially from the age of 50 to 55.

What is Benign Prostatic Hyperplasia a Sign of?

BPH is mainly a sign of aging in the case of males. It’s a normal condition that’s seen in adult males over 50. The exact reason behind the condition is still debatable. However, experts suggest that changes in male sex hormones that come with aging might be a factor.

People having a family history in regards to prostate issues might be more exposed to the risk of BPH.

The commonly experienced symptoms include:

  • Trouble in starting to urinate
  • Frequent urination
  • Sudden urgency to urinate
  • A weak flow of urine
  • Pain after ejaculation
  • Trouble in controlling the feeling to urinate

How Can Coffee Affect An Enlarged Prostate?

The stimulant caffeine in coffee affects an enlarged prostate by increasing the rate of urination, causing the person to pee more than usual.  It may also have an impact on the bladder sensation and contraction.

Stimulants are responsible for triggering certain changes in the regular functioning of the body system. Large doses of caffeine, for this reason, may result in affecting the muscles in the neck of the bladder. This will make a person urinate more.

Moreover, caffeine is a natural diuretic. This is why you get the sensation to pee more after having coffee. Even if the caffeine content doesn’t affect the prostate directly, if a person is already having issues with an enlarged prostate, the stimulant may irritate the organ.

The diuretic effect of the caffeine will also produce the rate of urination and you’ll get frequent urgency to urinate if you have BPH.

This study on the Effect of caffeine on bladder function in patients with overactive bladder symptoms showed that caffeine can promote early urgency to urinate and the symptoms are more prevalent in the case of individuals with overactive bladder.

It’s better to limit the consumption of caffeinated beverages to avoid any of these unwanted feelings if you’re having an enlarged prostate.

Is Drinking Coffee Bad For Your Prostate?

Drinking coffee isn’t necessarily bad for your prostate’s health, but overconsumption can lead to the irritation of the bladder and prostate. Since caffeine has diuretic effects, too much caffeine intake may even lead to urinary inconsistency.

There are several studies conducted on men that show that regular consumption of caffeine increases the urinary inconsistency in men compared to those who don’t drink it.

If you already have a prostate issue or BPH, the caffeine intake will worsen the symptoms and disrupt your urinary health.

If you still need the caffeinated boost, try to take the drink within mid to late morning. Remember, you must follow a proper schedule for ingesting caffeine since the stimulant has the ability to disrupt your body’s biological clock.

Even if it doesn’t cause problems to your prostate health, it might trigger other unwanted feelings such as headache, insomnia, vomiting, nervousness, anxiety, and so on.

The urgency to urinate more is already a symptom of caffeine overdose. So if you’re already having BPH, the caffeine will be more troublesome.

Do note that, although the caffeine may trigger the sensation of urgent and frequent urination, it’s not the cause of prostatitis.

Caffeine is indeed good for your overall and prostate health. Researchers have found that caffeine can inhibit cell growth while cafestol, kahweol can inhibit cancer growth.

One of the most important antioxidants in coffee, chlorogenic acid can inhibit DNA methylation.

The problems with coffee and caffeine will arise only if you’re already dealing with an enlarged prostate or taking too much of the beverage beyond the safely recommended quantity.

Coffee and Prostate Health can be a healthy mix.

How Does Caffeine Affect the Prostate?

Caffeine affects those who are already having an issue with benign prostatic hyperplasia since it can make the kidney produce more urine.

As caffeine is a natural diuretic, it can :

  • Overstimulate the Overactive Bladder
  • Increase the urgency to urinate more frequently
  • Increase the frequency of urination
  • Affect your hydration status
  • Deplete calcium in your body and result in an increase in excretion

Coffee, as a result, may act as a bladder irritant and be a bad choice for men having urinary issues. However, the consumption of coffee is bad only if you’re ingesting beyond your tolerance level and having other caffeine-containing stuff as well.

Caffeine may result to changes in excretory system
Caffeine may flush out more nutrients through urination from your body.

The effects on the body due to caffeine’s diuretic properties will get back to normal once the stimulant’s level in your bloodstream decreases. But if you’re on high doses of caffeine it’ll not only have control over your excretory system but also trigger unwanted health concerns such as:

  • Seizure
  • Headache
  • Anxiety
  • Nausea
  • Insomnia
  • Addiction

This is why the consumption of coffee should be checked and I personally feel 50-100 milligrams of caffeine is enough for the desired boost of the human body.

Simply put, if you’re a healthy individual limit your intake to 1-2 cups of coffee per day. You won’t be having any adverse side effects and this won’t affect your prostate health as well.

On the other hand, if you’re already having BPH or an enlarged prostate, curb your consumption to as much as possible. Consult with a health care provider for a better understanding of an intake portion for your body.

Is Decaf Coffee Good For The Prostate?

Decaf coffee can be good for prostate health since it contains other important antioxidants and nutrients. Also, it is absolutely not out of caffeine though the quantity may be small.

Many researchers believe that the connection between caffeine and prostate health is invalid. No matter which drinks people are having, caffeinated or decaffeinated, the participants that were taken under observation, showed similar results.

This is because coffee contains other essential antioxidants and plant-based chemicals that have health benefits such as preventing inflammation.

Decaf coffee is a blessing for people with lower urinary tract symptoms since it contains all the beneficial attributes of regular coffee minus caffeine.

The low caffeine content will show only a negligible diuretic effect and the urinary symptoms can be improved in the case of people with BPH.

The following table shows the caffeine content in different variations of coffee. It’s wise to choose your quick energy boost according to your body’s caffeine requirements and tolerance:

Type of CoffeeCaffeine Content (on average)
Brewed Coffee95 mg
Decaf Coffee2 mg
Frappuccino65 mg
Cold Brew155 mg
Espresso 75 mg
Instant Coffee63 mg

Can Coffee Help Prevent Prostate Cancer?

Numerous studies have found that coffee can help prevent prostate cancer. The meta-analysis of this 2014 study showed that high coffee drinking habit has been associated with a reduced risk of prostate cancer and also inversely associated to the fatal high-grade prostate cancer. Here the consumption of coffee was more than 4-5 cups a day.

Not everyone has to drink such a high amount of coffee. Since caffeine is a stimulant, the best benefits can be obtained when drank in moderation.

However, the final verdict can claim that caffeine indeed can reduce the risk of prostate cancer. It can’t surely resist the onset of the disease but can affect the risk rate up or down depending on the amount of caffeine consumed on regular basis.

The same study also states that the result isn’t applicable for someone who is an occasional drinker.

Since overdose of caffeine can lead to withdrawal symptoms, it’s better to check the body’s tolerance and drink accordingly. Remember, maintaining a healthy lifestyle habit is the key to remain fit and happy.

Caffeine alone can’t be a protective shield against fatal diseases.

A 2015 study shows that there exists an inverse relationship between the amount of coffee consumed and the risk of prostate cancer but only for the boiled coffee type.

Thus. how your coffee is being prepared is also an important factor. Adding addictive such as sugar, creamers, or milk may also degrade the nutritional content of the beverage and disrupt your sugar level.

Coffee also contains cafestol and kahweol that are well-known for cancer-fighting abilities and boiled coffee allows these essential chemicals to remain in your drink.

Is Tea A Better Option For Prostate Health?

Green tea and hibiscus tea are the best options for prostate health.

Coffee can be overall good for your health but since it has got the stimulant caffeine, you can’t depend on it as your go-to energy source. Apart from maintaining prostate health, coffee may also trigger your nervous and cardiovascular system negatively if consumed beyond the limit.

Switch your drink to a healthier option like green tea. It contains loads of important antioxidants and can help prevent prostate cancer.

For people with BPH or prostatitis, it’s important to curb caffeine consumption. Since caffeine may irritate the prostate and the bladder, it may worsen the BPH symptoms.

It will be wise to reduce caffeine consumption in such cases. If possible drink coffee and green or hibiscus tea in alternate and don’t depend on the coffee too much. This will help in improving your urinary health.

How Can I Improve My Prostate Health?

You can improve your prostate health by adopting a healthier lifestyle.

The prostate problem is one of the most concerning conditions for men, especially for the elderly ones.

As per reviews and expert suggestions, some of the important things to take notes of for better prostate health include:

  • Limit your caffeinated drinks. If possible, switch to green tea.
  • Exercise regularly
  • Loose weight
  • Take supplements if needed
  • Reduce stress
  • Include plant-based meals in your diet more often

As prostate health depends on your diet and lifestyle, make a goal to improve it. Some things are beyond our control but we can try our best to lower the risk of any adverse condition by taking proper care of the body.


Coffee comes with a lot of health benefits when consumed timely and in proper amounts. However, having BPH or an enlarged prostate calls for necessary changes in your diet for the proper management of good health.

It’s always wise to avoid risk and consume the foods and drinks useful for the body. Findings from several studies may conclude that the essential compounds in coffee may overall benefit prostate health.

Healthy individuals should check their caffeine consumption to reap the best outcomes. Coffee alone won’t cause the enlargement of the prostate but if you’re already having an issue with the organ, the caffeine may worsen the symptoms.

Choose the healthiest variety of coffee to prevent any unwanted health concerns.

For clearing out any of the underlying confusion regarding your prostate health, consult your doctor for:

  • A healthy dietary recommendation
  • Types of exercises needed
  • Intake quantity of caffeine
  • Medical screening according to your age

Considering both the positive and negative impacts of caffeine on men’s health, my personal suggestion is to curb the consumption according to the body’s condition. You can always substitute caffeine with other healthy varieties of teas.
