Obesity
Go to the last point. If you drink less water, you increase your appetite, which can lead to obesity. Additionally, dehydration slows down your metabolism, which contributes to weight gain.
Bad skin condition
If you are dehydrated, your skin cells are also dehydrated. This means your skin is dry, stretched and relaxed, as well as fine lines and loose skin. Water also helps detoxify the body, so not drinking enough water can cause toxins and rashes.
Digestive problems / constipation
Problems with the digestive system
Water keeps your digestive system healthy and helps food move through the digestive system. It also makes stools softer and easier to pass. Dehydration can relax muscles and reduce their movement throughout the body. This can lead to chronic bloating, flatulence and gas.
