Question: The Importance of Water
Having PCOS can put you at risk for a number of related metabolic conditions, including diabetes, heart disease, high cholesterol and metabolic syndrome. In addition, many women with PCOS have weight issues. Taking in sufficient fluids is an important part of maintaining a healthy diet and lifestyle.


Water is a major component of every body cell, tissue and organ. It plays an important role in almost every body function, including:
  • Temperature regulation
  • Transportation of oxygen and nutrients through the blood
  • Acting as a necessary component of chemical reactions
  • Aid in elimination of waste through urine and feces
  • Lubrication of joints
  • Acting as a major component of body fluids such as mucus and tears
  • Giving the cells their shape and stability

Daily Requirements

Generally speaking, people should consume approximately 2 to 3 liters of fluid each day. This does not take into account a person’s medical condition, exercise habits, and living environment (high altitude location or extremely hot area). Day-to-day activities may also increase ones need for fluid. For example, water requirements are increased when flying or during strenuous exercise.

Other sources of water

Besides drinking water, we take in a lot of fluids in the food that we eat. Many fruits and vegetables have a high water content, another reason why we should eat a lot of fresh produce. One hundred percent fruit juice also contributes fluid to our diet, as do other beverages such as coffee and soda, though in small amounts. Caffeine, however, is dehydrating and can cause you to lose water. Soda and many fruit juices are a huge source of wasted calories in our diet. Try seltzer water with a splash of 100% fruit juice instead of soda for flavor without as much of a caloric punch.
