Is This an Emergency? If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Loose, Watery Bowel Movements

Taking vitamin E in higher doses can cause diarrhea, which is defined as loose or watery bowel movements 3. Mild diarrhea will last for a few days, but a severe case may take longer. Diarrhea makes you feel weak and causes you to lose more fluids than you consume, resulting in dehydration. Common signs of dehydration include light-headedness, sunken eyes, decreased urine output and dry mouth. If you have any of these symptoms, discuss these with your health care provider immediately. Tell him if you have blood or pus in your stools, stomach pain that persists even after having a bowel movement or diarrhea accompanied by a fever of over 101 degrees Fahrenheit.
