Urinary Tract Infections (UTIs) are common bacterial infections known for symptoms like frequent urination and burning sensations. However, they can also cause unexpected symptoms such as nausea. This can happen because UTIs, resulting from bacteria entering the urinary system, may lead to inflammation that affects nearby organs, such as the digestive tract.

Knowing this connection is crucial for early symptom recognition and proper treatment. This article looks deeper into the question, ‘Can a UTI cause nausea?’ and explains how UTIs can induce nausea. It also discusses effective treatments available to alleviate these symptoms. So read on.

Factors contributing to nausea & UTI

While nausea is not typically listed as a primary symptom of UTIs, some individuals may experience it as part of their overall discomfort. Here are a few reasons why nausea might occur in conjunction with a UTI:

Inflammation

UTIs lead to urinary tract irritation, which may spread to the tissues around the bladder and its lining and cause inflammation. This inflammation occurs when the body’s immune response sends white blood cells to fight the infection, causing swelling and irritation. These effects can impact nearby nerves, sending pain signals to the brain and potentially causing nausea.

Kidney infections

UTIs can develop into Pyelonephritis when bacteria move from the bladder up through the ureters to the kidneys. This can occur due to incomplete bladder emptying or urinary tract abnormalities. When bacteria reach the kidneys, they can cause an infection characterized by symptoms like high fever, chills, and upper back discomfort. The body’s immune response to this more severe infection can induce nausea as a secondary symptom, alongside the direct impact of inflammation and irritation in the urinary tract.

Fact
Pyelonephritis is a bacterial infection of the kidneys, typically arising from an Urinary Tract Infection. It is characterized by severe symptoms such as fever and back pain.

Medication side effects

Antibiotics may be recommended to patients seeking therapy for their UTIs to treat bacterial infections. An upset stomach and nausea are two gastrointestinal side effects that some medications might cause. 

Dehydration

UTIs can cause discomfort while urinating, prompting some people to drink less to reduce the frequency of bathroom trips. However, this dehydration can worsen nausea or exacerbate existing symptoms. Maintaining adequate fluid intake is crucial to help flush out bacteria and alleviate symptoms effectively.

Symptoms of UTI

Along with nausea, a person may suffer these additional UTI symptoms including:

  • Cloudy or bloody urine, which may emit a foul or strong odor
  • Some individuals may experience a low-grade fever
  • Pain or burning sensation during urination
  • Cramping or pressure in the lower abdomen or back
  • Frequent strong urge to urinate, even shortly after emptying the bladder

If the infection spreads to the kidneys, symptoms may include:

  • Chills, shaking, or night sweats
  • Fever above 101°F (38.3°C)
  • Pain in the side, back, or groin
  • Vomiting
  • Occasional severe abdominal pain
Warning
If UTI symptoms return shortly after completing a course of antibiotics, contact your healthcare provider immediately. This recurrence may indicate that the infection has not been fully treated or could suggest antibiotic resistance, necessitating prompt medical assessment, and potential treatment adjustment.

Prevention and management

If you are feeling nauseous due to a UTI, here are some ways to help you feel better:

  • Take pain relievers: Try over-the-counter medicines like Acetaminophen or Ibuprofen (Brufen 400 mg) to lower fever and reduce pain
  • Use a heating pad: Apply a warm pad on your lower belly to soothe discomfort and lessen nausea
  • Stay hydrated: Drinking plenty of water helps flush bacteria from your urinary tract
  • Empty your bladder often: Urinate regularly and fully to stop bacteria from growing and causing more nausea

Conclusion

UTIs, commonly known for urinary symptoms, can also lead to inflammation that affects nearby organs, such as the digestive tract, triggering nausea. Factors contributing to nausea during UTIs include inflammation from the urinary tract to surrounding tissues and potential kidney infections like Pyelonephritis. 

Prompt medical attention is essential if nausea occurs alongside a UTI, as it may indicate a more serious infection requiring immediate treatment to prevent complications. Managing symptoms with pain relievers, hydration, and timely urination can help alleviate discomfort and support recovery. By staying informed and proactive, individuals can better navigate UTI symptoms and seek appropriate medical care when needed.

Frequently Asked Questions

Does UTI make you nauseous?

Yes, UTIs can make you nauseous. The infection can cause inflammation in the urinary tract and nearby organs like the digestive system. This inflammation and the body’s immune response can trigger feelings of nausea. It’s important to seek medical advice if nausea accompanies symptoms of a UTI to prevent complications.

How long does UTI sickness last?

UTI sickness typically lasts from a few days to a week. Antibiotics usually start improving symptoms within a few days, but it’s important to finish the full course to clear the infection completely. Some UTIs may clear on their own without treatment, but there’s a risk of complications without appropriate treatment. 

Can a UTI cause bloating and nausea?

Yes, a UTI can cause bloating and nausea. The infection may lead to inflammation in the urinary tract and adjacent organs, triggering these symptoms. If experiencing such symptoms, consult a healthcare professional for proper diagnosis and treatment.

Can antibiotics give you nausea with UTI?

Yes, antibiotics used to treat UTIs can sometimes cause nausea as a side effect. This is common but not experienced by everyone. Taking antibiotics with food or adjusting the timing of doses can help reduce nausea.

Does a kidney infection cause nausea?

Yes, a kidney infection (Pyelonephritis), which can develop from an untreated UTI, often causes nausea. Alongside symptoms like high fever and back pain, nausea is a sign that the infection has spread and requires prompt medical attention to prevent serious complications.
