Can Caffeine Lead To UTI Symptoms?- A Comprehensive Guide

A urinary tract infection, commonly termed a UTI, is an infection of the urinary tract and system. (1)

The urinary system is responsible for cleaning the blood, filtering waste from the body, generating urine, regulating blood pressure and controlling blood volume, among other things. The kidneys, bladder, ureters, urethra, and renal pelvis comprise the overall urinary system. 

Many patients may also have questions about their day-to-day lifestyle such as ‘Can Too Much Caffeine Cause UTI Symptoms?

1. Causes Of A UTI:

Many different types of bacteria can be found in the rectum and vagina, as well as on the surrounding skin.

Harmful pathogens and bacteria may then penetrate the urethra and move to the bladder. 

Although the urinary system is intended to keep dangerous pathogens and bacteria out, these barriers may occasionally fail and bacteria may be able to enter the body through the urinary system and spread.

This then causes a urinary tract infection. (2)

Your risk of developing a UTI may also increase due to one or all of the following:

  1. Urinary-Related Diseases 
  2. Poor Personal Hygiene 
  3. Previous History of UTIs 
  4. Being Sexually Active


2. Symptoms Of A UTI:

If a patient develops a urinary tract infection, they may experience any of the following symptoms: (3)

  1. Fever
  2. Fatigue
  3. Pungent urine
  4. Increased urge to urinate
  5. Bloody urinal discharge
  6. A burning sensation when urinating
  7. Cloudy urine

A widely asked question: Can anxiety cause UTI symptoms? Yes. 


3. Can Caffeine Cause UTI Symptoms? 

Patients may be wondering, ‘Does caffeine cause UTI symptoms?’

Excessive caffeine consumption may lead to worsened urinary tract infection symptoms. (4)

UTI symptoms may be worsened as a result of dehydration or insufficient urination.
Caffeine substantially dehydrates the body by altering fluid retention levels, thus causing your body to expel liquids before they can be ingested properly.

Caffeine intake may also cause certain UTI symptoms such as increased blood pressure and an increased urge to urinate as it is a diuretic.

Therefore, although consumption of coffee may not necessarily cause UTI symptoms, it may irritate the lining of the urinary tract and make pre-existing UTI symptoms worse.

4. How Much Caffeine Can Be Safely Consumed?

The FDA has specified 400 mg per day for healthy adults (roughly four or five cups of coffee) as a safe quantity to consume per day without dealing with health issues.

However, there is a large range in both how receptive individuals are to caffeine's effects and how quickly they are able to metabolize it. (5)

Certain medical problems, as well as some medications, might make people more susceptible to caffeine's effects.

Therefore, patients wondering ‘Can too much caffeine cause UTI symptoms?’ can hence vary UTI symptoms caused by caffeine by consuming less than 400 mg of caffeine per day.

5. Alternatives To Reduce Caffeine Intake:

Many people drink coffee or some alternative caffeinated beverage on a day-to-day basis.

However, there are numerous alternative beverages that patients can try to reduce caffeine intake. 


  • Matcha Tea

Matcha tea is an extremely popular coffee alternative. Matcha is a green powder formed from crushed tea leaves that may be substituted for coffee.

In contrast to brewed green tea, you consume the complete leaf. As a result, the antioxidant content is much greater than that of coffee. 

Matcha has also been linked to a decreased prevalence rate of type 2 diabetes, as well as weight loss.


  • Apple Cider Vinegar

Apple cider vinegar has been widely used to treat UTI. 

Apple cider vinegar is a non-caffeinated beverage made from fermented acetic acid-containing apples. It has been shown to increase insulin sensitivity and improve glucose levels. 

Patients should always dilute apple cider vinegar with water to avoid damage to teeth.


  • Lemon Water

Replacing caffeinated drinks with lemon water can be extremely beneficial. Lemon water is high in vitamin C and extremely low in calories. (6)

Vitamin C is an antioxidant that strengthens your immune system and shields your skin from UV rays. 

Other fruits and herbs, such as cucumbers, mint, watermelon, and basil, can be used to further flavour lemon water to make it more appealing.
