Water Retention: 30 Foods to Eat

What do you eat for water retention? If you have swelling in your body in the form of swelling of the legs, or just swollen ankles or swollen feet, swelling of the arms, or just swollen hands, face puffiness and stomach bloating, then changing what you eat can help you drop the water weight and reduce the swelling visibly. Results can take as little as one week to show, provided you eat right and are consistent in your efforts.

Why does the body retain water?

Water retention, also called fluid retention or, more simply, water weight, is the retention of excess amounts of fluid in the body. For the most part, retention of excess fluid leading to visible swelling in various areas of the body occurs when there is a too high a intake of sodium, usually from added salt and eating lots of processed foods.

What to eat for water retention

Sodium normally helps the body retain fluid and is needed to regulate fluid levels everywhere in the body; it is of vital necessity for maintaining normal blood pressure numbers, normal blood volume and regulating the activity of nerve cells and essential cellular processes. Excessive levels cause the body to accumulate fluid and lead to high blood pressure, swelling in the arms, legs, hands, ankles, feet, face and abdomen, among other side effects.

Of course, it’s not just water retention behind visible swelling occurring in different parts of the body. For example, face puffiness is also commonly caused by seasonal pollen allergies and represents one of many symptoms of allergic rhinitis. Or it can be a sign of inflamed sinuses or a sinus infection. Face puffiness and swelling in the arms, legs and abdomen is a common side effect of medication such as corticosteroids used to treat seasonal pollen allergies and other types of allergies, asthma, autoimmune conditions, and inflammation in the body.

Abdominal swelling or bloating can also be caused by infestation with intestinal worms and other intestinal parasites, dairy intolerance, lactose intolerance, wheat sensitivity, gluten allergies or diseases such as cirrhosis of the liver, liver cancer, ovarian cancer etc.

Abdominal swelling is also common during ovulation as part of the natural hormone fluctuations during menstruation; it’s common to gain between 1 kilogram and 3 kilograms of fluid during this time of the month and just drop it soon after the ovulatory cycle ends. Pathological changes in hormone profiles and levels also account for increased retention of fluid e.g. thyroid issues. Water retention is also common when simply eating more, more notably if you have processed foods or salty foods.

There are many caused behind what seems to be accumulation of fluid in the body, some harmless, some not so much. As such, it is imperative you do get water retention investigated at the doctor’s if it’s a recent development, uncharacteristic of your body up until that time, more so if you cannot connect it to significant dietary changes.

Magnesium and potassium are electrolytes that regulate body fluid levels and counteract the water-retaining effects of excess sodium in the diet. Oatmeal in the morning for breakfast help balance fluid levels in the body and flush out excesses, while also regulating bowel movements for a visibly flatter stomach in a matter of days. See more ways oatmeal helps you get a flat stomach.
