Medical News Today explains that people with protein deficiencies can struggle with water retention because their bodies are unable to get the water from the tissue spaces back into the capillaries. This is the key reason you see distended stomachs on malnourished people.
5. Try Vitamin B6.
This vitamin has been shown to be effective at reducing water retention in women with PMS and can easily be gained from bananas, potatoes, walnuts and meat – or a supplement.
