What Is Water Retention?

Water retention (also called fluid retention or edema) happens when excess fluid builds up in tissues. You may notice:

• Swelling in feet, ankles, and legs
• Puffy face or eyelids
• Bloating around the abdomen
• Feeling of heaviness and tightness in the skin

Short-term mild water retention can be linked to:

• High-salt meals (e.g., packaged snacks, pickles, papad)
• Hormonal changes during periods
• Sitting or standing for long hours (desk jobs, travel)
• Hot weather and dehydration

Chronic or severe water retention may be related to underlying health issues such as kidney disease, heart failure, liver disease, or certain medications. In such cases, you must consult a doctor and not depend only on home remedies.

How Do Diuretic Foods Help?

Diuretics are substances that help your kidneys produce more urine, allowing your body to get rid of excess water and salt. While doctors sometimes prescribe diuretic medicines, there are also natural diuretic foods and drinks that gently support fluid balance.

Natural diuretic foods may help:

• Reduce puffiness and mild swelling
• Ease bloating and a feeling of heaviness
• Support kidney function and detoxification
• Balance electrolytes when consumed wisely

However, they are not a replacement for medical treatment. If your water retention is sudden, painful, or accompanied by breathlessness, chest pain, or fatigue, seek medical help immediately.

8 Best Natural Diuretic Foods (Indian-Friendly Choices)

• Limit green tea to 1–2 cups per day to avoid excess caffeine

Other Helpful Lifestyle Tips to Reduce Water Retention

1. Control Salt Intake

• Limit salted snacks (namkeen, chips, bhujiya), pickles, papad, and processed foods
• Avoid adding extra table salt on top of cooked food
• Use herbs, lemon, and spices for flavor instead of extra salt

2. Stay Hydrated

It may sound strange, but drinking enough water actually helps reduce water retention. When you are dehydrated, the body holds on to water.

• Most healthy adults should aim for 2–3 litres of fluids daily (unless restricted by a doctor)
• Include water, herbal teas, buttermilk, and watery fruits

3. Move Your Body

• Avoid sitting or standing in one posture for long hours
• Walk for 5–10 minutes every hour if you have a desk job
• Elevate your legs on a pillow when lying down to reduce ankle swelling

4. Check Hormonal and Medical Causes

If water retention is frequent, severe, or associated with other symptoms, consult a doctor to rule out:

• Kidney problems
• Heart conditions
• Liver disease
• Thyroid or hormonal imbalances
• Side effects of medicines (e.g., some blood pressure pills, steroids)

Who Should Be Careful with Natural Diuretics?

Even natural diuretic foods should be used cautiously in certain people:

• Those with chronic kidney disease or on dialysis
• Patients with heart failure or on strict fluid control
• People taking blood pressure medicines or prescribed diuretics
• Pregnant women with swelling and high blood pressure

Always speak to your doctor before making major dietary changes if you have any chronic health condition.

FAQs

Question: Can I rely only on diuretic foods to treat water retention?

No. Natural diuretic foods can help with mild, short-term water retention due to factors like high-salt meals, heat, travel, or PMS. But persistent or severe swelling can indicate serious conditions such as kidney, heart, or liver disease. In such cases, medical evaluation and treatment are essential.

Question: How much water should I drink if I have water retention?

Unless your doctor has restricted fluids, most healthy adults should aim for about 2–3 litres of water and other healthy fluids per day. Drinking too little can worsen fluid retention because the body starts conserving water. People with kidney disease, heart failure, or on diuretics should follow their doctor’s specific fluid advice.

Question: Are there any side effects of taking natural diuretics every day?

When consumed as part of a balanced diet, foods like cucumber, lemon water, and coriander seed tea are generally safe. However, overuse of herbal diuretic teas or excessive fluid intake can disturb electrolyte balance and stress the kidneys, especially in people with existing health issues. Always use moderation and consult your doctor if you have chronic disease or take regular medicines.

Question: Does salt directly cause water retention?

Yes, high salt (sodium) intake is one of the most common causes of water retention. Sodium attracts and holds water. Processed foods, restaurant food, and salty snacks often contain more sodium than homemade meals. Cutting down salt usually reduces swelling and bloating over time.

Question: Which Indian foods should I avoid if I have water retention?

Limit very salty and processed foods such as packaged namkeen, chips, instant noodles, pickles, papad, processed meat, and bakery items like biscuits and bread with added salt. Also be careful with very sugary drinks and sodas, as they can indirectly worsen water retention and weight gain.

Question: When should I see a doctor for swelling or water retention?

See a doctor immediately if swelling:

• Comes on suddenly
• Is painful or only on one leg
• Is associated with breathlessness, chest pain, or rapid weight gain
• Occurs with decreased urine output, fatigue, or confusion

Long-standing but mild swelling should also be evaluated to rule out kidney, liver, heart, or hormonal issues.
