For a kidney infection, avoid sugary items (soda, candy), high-sodium processed foods (canned soups, deli meats, pickles), excess caffeine, alcohol, and potentially bladder irritants like citrus and tomatoes, as these can worsen symptoms or strain the kidneys, with sugar potentially fueling bacterial growth. Focus on plenty of water, but limit potassium-rich foods (bananas, oranges, avocados) and phosphorus-heavy items (dark sodas, whole grains) if kidney function is compromised, as these minerals can build up.
High-potassium foods
Foods like bananas, oranges, potatoes, and avocados are particularly high in potassium and should be consumed sparingly during a kidney infection. Opt for low-potassium alternatives such as apples, berries, cauliflower, and courgettes to maintain balance without overloading your kidneys.
To relieve pregnancy kidney pain, prioritize hydration, use pregnancy-safe pain relievers like acetaminophen as directed by your doctor, apply a heating pad, get rest, and wear loose clothing, but always consult your doctor first for severe pain, fever, or vomiting, as it could signal a kidney infection or stones needing specific treatment like antibiotics or procedures.
How Are Acute Kidney Infections Treated? Children are typically given oral antibiotics to take at home. However, if the infection is advanced, a child may receive intravenous (IV) antibiotics in the hospital.
The main treatment for a kidney infection is antibiotic tablets, which you'll usually take for 7 to 14 days. You'll usually feel better after about 2 weeks. People who are older or have underlying conditions may take longer to recover.
Kidney infections tend to make people much sicker than bladder infections do. A kidney infection is also more serious because it can cause lasting damage if it is not treated quickly. Follow-up care is a key part of your child's treatment and safety.
If you have chronic kidney disease (CKD), avoid high-sodium, high-phosphorus, and potassium-rich foods. Examples include processed snacks, cola, bananas, and canned soups. Always consult your healthcare provider for personalized guidance on your diet.
Serious kidney infections may require a hospital stay so you can get bed rest and adequate fluids. “Along with taking an antibiotic, speed healing by drinking plenty of water,” Erb says. “Liquids expel bacteria from your urinary tract.
Water is the best beverage for supporting kidney health. It helps flush out toxins, maintains electrolyte balance, and prevents dehydration. Drinking at least 8–10 glasses of water daily is essential for anyone in recovery, especially those enrolled in an Alcohol Treatment Program or Drug Rehab Programs.
Place a heating pad on your back, abdomen or side to help reduce kidney pain. Take pain relievers. To ease fever or discomfort, take over-the-counter pain relievers, such as acetaminophen or ibuprofen (unless you have known liver or kidney damage and are not supposed to use these medications).
This pain can radiate to your back, groin or lower belly (abdomen). You may have a dull pain that doesn't stop. But you may also feel sharp pain off and on. Kidney colic can come in waves.
See your doctor immediately or go to your local hospital emergency department if you have kidney pain and: you have a fever or feel very unwell. you are unable to pass urine. the pain is on both sides of your body.
A kidney-friendly diet doesn't have to be restrictive. By including the right fruits in your meals, you can support kidney function, reduce inflammation, and stay hydrated. Choose low-potassium, high-antioxidant fruits like berries, apples, and grapes, and avoid high-potassium options like bananas and oranges.
Kidney-friendly snacks at the grocery store
It's very typical to feel like you can't move at all when you have a kidney infection. The fatigue is so bad that all you may want to do is sleep. Sleep is essential for healing, so it's your body's way of telling you what it needs.
Where do I feel kidney pain? You feel kidney pain near the middle of your back, just under your ribcage, on each side of your spine where your kidneys are. Your kidneys are part of the urinary tract, the organs that make and remove urine from the body.
Sex can make a UTI worse
You don't have to be sexually active to get a UTI – anything that brings bacteria in contact with your urethra can cause infection. However, sexual activity increases your risk of complications and potentially puts your partner at risk as well.

Hospitalization (Severe Cases): Severe kidney infections may require hospitalization, especially if you are experiencing high fever, severe pain, vomiting, or signs of sepsis. You can receive intravenous antibiotics and other treatments under close medical supervision in the hospital.
