Balancing Water and Electrolytes for Urinary Health
January 12, 2026
Have you gotten your share of bicarbonate today? How about chloride, and phosphates?
These minerals are among the seven key electrolytes your entire body, including your urinary system, depends on to be healthy.
Upsetting the balance of your electrolytes, (too few or too many of them), can contribute to health issues involving your kidneys, bladder, and urinary tract. This indicates the important role of electrolytes: Among other things, they nourish your cells and remove waste from them, support nerve function, and steady your heart rate.
They need water to do that.
What’s Dehydration Got to Do with It?
The key cause of electrolyte imbalance is dehydration, either through excessive sweating, not drinking enough water, gastrointestinal issues such as diarrhea, and vomiting.
Drinking fluids helps your cells convert food into energy, support growth, and generally maintain a healthy life. Fluids also flush waste and toxins from your urinary system. While occasional dehydration is easily managed, chronic dehydration – which researchers say affects as many as 28% of Americans – may require medical intervention.
When you’re dehydrated, your metabolism slows, bacteria in the gut microbiome multiply, and the organs in your urology system could suffer.
Urology Illnesses Linked to Dehydration
The amount of water you need can vary based on your body type, your activity, your age, and where you live (climate and elevation). If you consistently fail to get enough fluids, the following conditions can occur.
Kidney stones – These small, hard crystals form due to a high concentration of minerals such as salts, calcium, and uric acid. When you are dehydrated, the kidneys lack enough fluid to flush them out, as well as to balance electrolytes, and the minerals accumulate and bind. Kidney stone symptoms include sharp pain in the back and side, blood in the urine, and frequent, urgent urination. Click here to learn more about kidney stones and treatments.
Serious kidney diseases – When you are dehydrated, your kidneys respond by holding onto fluids they extract from your blood. Because your kidneys typically flush waste from your blood, this lack of fluids means the waste builds up instead. Further, when you are severely dehydrated, blood and nutrients have trouble making it to the kidneys. Note: Those with chronic kidney disease (CKD) may need to limit water and regulate potassium, because the body won’t make urine in this state and the kidneys are less able to remove excess potassium. Symptoms of CKD include fatigue, dry skin, making less urine, blood in the urine, and swollen hands, feet, and ankles. Read about healthy eating and drinking for your kidneys in our blog.
Agonizing urinary tract infection (UTI) – Because kidneys produce less urine when you are dehydrated, bacteria such as E. coli are able to linger and grow into your bladder. Additionally, that highly concentrated urine can irritate and weaken your urinary tract. Water improves the effectiveness of antibiotics to fight a UTI. While common among women, UTIs can be more serious as women age. Symptoms include painful or burning urination, producing little urine despite an urge to go, and cloudy urine. You can read more about UTIs here.
Painful bladder inflammation – When dehydration causes your body to make less urine, a high balance of toxins and minerals remain. These substances can irritate and inflame your bladder’s lining. Patients who live with interstitial cystitis (IC), also known as painful bladder syndrome, should stay hydrated in order to manage the symptoms, such as pelvic and bladder pain (including during intercourse), bladder pressure, and a frequent urge to urinate. Hydration manages IC symptoms because it dilutes urine.
You should consult a urology specialist if you recognize any of these symptoms.
Recognizing Dehydration
Common signs of dehydration:
- Excessive thirst
- Urine that is darker than pale yellow
- Urinating less often than usual
- Lightheadedness and headaches
- Fatigue
- Sunken eyes and/or cheeks
- Dry skin; skin that doesn’t flatten after you pinch it
- Muscle cramps
Hydration Helper: High- and Low-Electrolyte Foods and Drinks
Drinking lots of water is the easiest solution to dehydration. The U.S. Academies of Science, Engineering, and Medicine recommend 11.5 cups (for women) to 15.5 cups (for men) a day.
However, if you need the quick-hydrating boost of an electrolyte-packed food or drink, consider these natural options that are high in potassium:
Fruits – Kiwi, avocado, bananas, apricots, and oranges are ideal.
Vegetables – Beets (and their greens), carrots, spinach, sweet potatoes, and baked potato
Proteins – Beans, shellfish, fish (especially skipjack tuna, shad, and rainbow trout)
Drinks – Tomato juice, orange juice, reduced-fat milk (including plant milks), and unsweetened coconut water
You can make your own electrolyte-rich beverages by blending some of the above.
If you suffer from chronic kidney disease or failure, be aware that you need to moderate your potassium. Talk to your doctor about recommended dietary changes and the risk of developing hyperkalemia, a medical condition caused by kidney disease in which too much potassium builds in your blood.

Which Electrolytes are Best?
The electrolyte products market is booming. Many of these products, such as LMNT and Gatorade Endurance, are designed to replace or replenish electrolytes when you’re very active and sweating. Others, including Ultima and Ucan, are made for everyday use and light activity.
Not everyone requires electrolyte drinks to remain hydrated, however. If you sweat a lot, live at high altitudes, or generally do not drink enough water, electrolyte drinks will restore what you lost through dehydration. (Hint: Muscle twitching and muscle cramps signal a need for electrolytes.) Effective electrolyte drinks include sodium, potassium, magnesium, and chloride.
In a pinch, you can mix water with pretzels or another salty snack.
Other tips for good hydration:
- Dilute your drinks. Alcohol speeds up urine flow and interferes with the kidneys’ ability to balance electrolytes. When drinking alcohol, alternate it with water and do not drink on an empty stomach.
- Check your medications. Several drugs can cause dehydration, including blood pressure medicines (beta blockers), antipsychotics, diuretics, and anticholinergics (for asthma, COPD, overactive bladder, and IBS).
- Resolve to drink more water. Four out of 10 people older than 65 have chronic dehydration, UCLA Health reports. As you age, it becomes harder for your body to hold onto water, and dehydration results.
Dehydration isn’t just a summertime concern. Even in winter your electrolytes can become imbalanced. Restore them with the right fluids.
