Water pills are drugs that are frequently used to treat edema, liver and kidney issues, high blood pressure, and other heart-related problems, but are also sometimes used to reduce water weight. Although these medications can be effective at treating a number of conditions, they may also result in some undesirable reactions. Some of the side effects of water pills can include frequent urination or dehydration, stomach or digestive complaints, and flu-like symptoms.
Since this type of medication is used to flush excess salt and water from the system, some of the side effects of water pills may be the result of a deficiency in certain minerals like sodium or potassium. The symptoms of a sodium deficiency may include muscle cramps, fatigue and disorientation, nausea, and headaches. Over time, this deficiency may also cause seizures, a decrease in muscle functioning, and neurological complications. Potassium deficiencies can result in diarrhea or vomiting, depression, nervousness or irritability, edema, or salt retention. Sometimes people may experience an increase of heart-related problems such as an irregular heartbeat, lowered blood pressure, or, in rare cases, cardiac arrest.
Although there are some side effects of water pills that may be relatively harmless or easily treated with a secondary medication or supplement, others may require medical intervention. For instance, a doctor should be contacted right away if the patient experiences flu-like symptoms such as a sore throat, cough, or fever, or if the patient notices a skin rash, ringing in the ears, unusual bleeding, or bruising of the skin. Some side effects may be resolved over time, but a doctor should be contacted if they become persistent or severe. These symptoms can include an increase of perspiration, extreme fatigue or weakness, blurred vision, or confusion.
Urinary and hydration-related side effects of water pills are common and usually resolve on their own, but may also require medical attention if they become severe. One of these issues includes frequent urination, which usually passes within a few hours of taking these medications. Dehydration, on the other hand, often requires a visit to a doctor or emergency room. The symptoms of dehydration can include excessive thirst or dry mouth, a marked decrease in urination or dark-colored urine, constipation, or dizziness. Although milder cases of dehydration may be taken care of at home with drinks containing electrolytes and carbohydrates or juice, more severe cases may require fluid replacement through an intravenous (IV) line.
How Much Water Should I Drink While Taking Water Pills?
Although you may think that you need to increase your water intake to compensate for the loss of fluid when you take water pills, this is not the case. You must keep your hydration levels balanced, so it's important to maintain a normal water intake. Over or under consuming fluid can cause dehydration or reverse the effects of water pills. Most healthy adults should aim for eight glasses of water each day when taking water pills to maintain hydration, although doctors may advise patients with certain conditions such as heart failure to consume slightly less water.

- Dark yellow or brown urine
- Dry mouth
- Excessive thirst

Should You Change Your Diet While Taking Water Pills?
Your diet may need to change depending on which type of water pill you take.

A medical professional can determine which type of diuretic is best for you.
Are Water Pills Bad for Your Kidneys?
Taking water pills is not directly harmful to your kidneys, but if you become dehydrated while taking them, dehydration can have a negative impact on your kidney function. Water helps the blood vessels remain open so that blood can carry nutrients to the kidneys.
Mild dehydration can reduce the efficiency of kidney function. Severe dehydration may cause kidney damage. Chronic dehydration can cause permanent kidney damage.
Dehydration causes wastes and acids to accumulate in the body. These substances may clog the kidneys with muscle proteins. Dehydration may also contribute to the development of urinary tract infections and kidney stones. Both of these conditions can lead to kidney damage. Avoiding dehydration can help prevent these issues.
What Are Thiazide Diuretics?
Thiazides are the most common type of water pills. They are usually used to treat high blood pressure. They work by reducing fluids in the body and by relaxing blood vessels. They are sometimes combined with other blood pressure medications, such as chlorthalidone, metolazone, hydrochlorothiazide and indapamide.
What Are Loop Diuretics?
Loop diuretics are used for treating heart failure. Torsemide, bumetanide and furosemide are types of loop diuretics.
What Are Potassium-Sparing Diuretics?
Potassium-sparing diuretics reduce fluid levels in the body without the associated potassium loss that often occurs with other water pills. They are usually prescribed to people who are at an increased risk of low potassium levels.
This type of water pill isn't as effective at lowering blood pressure as other types. For that reason, it is often combined with other blood pressure medications. Examples of potassium-sparing diuretics include amiloride, spironolactone, triamterene and eplerenone.
Which Drugs Interact With Water Pills?
Medications, herbs and supplements sometimes have undesirable interactions with water pills. Some medications known to interact with waters pills are cyclosporine, lithium, antidepressants, digoxin and other blood pressure medications.

What Is Water Retention?
Water retention, or edema, is a condition where the body retains too much water. Water retention may cause bloating, swelling or puffiness.
What Causes Water Retention?
Water retention can be caused by several different things.
The changes in cabin pressure that occur during flight and extended periods of sitting can cause water retention.
Menstrual Cycle and Hormone Changes
Changes in hormone levels, such as those experienced at different points in the menstrual cycle or pregnancy, can cause water retention. Many people who menstruate experience water retention as a symptom of pre-menstrual syndrome.
Water retention can be a side effect of medications such as chemotherapy treatments, blood pressure medications, over-the-counter pain relievers and antidepressants.
Deep Vein Thrombosis
Clots in veins can cause DVT which may present as swelling in the leg.
Sitting or Standing for Extended Periods
Gravity causes blood to pool in the lower extremities. Movement helps keep blood circulating. When people sit or stand for too long, poor circulation can lead to water retention.
Over-Consumption of Sodium
Too much sodium in the diet can cause water retention. Excess dietary sodium is usually consumed by eating too many processed foods, consuming soft drinks or adding a large amount of table salt to food.
When the heart has difficulty pumping enough blood, the lack of circulation can cause water retention.
Changes in weight and weight distribution during pregnancy can cause water retention in the legs if you don't move regularly.

There are several common symptoms of water retention:
- weight changes
- swelling in the feet, legs or ankles
- stiff joints
- indentations in the skin
What Are the Consequences of Water Retention?
Chronic water retention can be a sign of serious health conditions, such as deep vein thrombosis, fibroids or pulmonary edema. Water pills are often prescribed to treat chronic water retention. Doctors may also prescribe birth control pills or supplements.
How To Prevent Water Retention?
The most common recommendation for avoiding water retention is to consume 2,300 milligrams of sodium or less per day. Increasing your consumption of potassium and magnesium-rich foods, such as bananas, tomatoes, avocados, leafy vegetables and sweet potatoes may also help.
Research suggests that vitamin B-6 supplements may reduce water retention. Consuming the protein albumin may also help with maintaining balanced hydration levels. Elevating your feet may help avoid swelling in the legs while sitting. Wearing compression leggings or socks can also reduce swelling in the legs.
