When you don’t drink enough water, your body becomes dehydrated, affecting many essential functions and leading to several noticeable symptoms.
Common Symptoms of Dehydration
- Increased Thirst and Dry Mouth: By the time you feel thirsty, your body is already in the early stages of dehydration. A dry or sticky mouth and lips are also common signs.
- Fatigue and Low Energy: Water transports nutrients and oxygen to cells. When you are dehydrated, your blood volume decreases, requiring your heart to work harder to pump blood efficiently, leading to tiredness and sluggishness.
- Dark-Colored Urine and Reduced Urination: Your kidneys retain more fluid to conserve water, making your urine darker yellow or amber and more concentrated. Ideally, urine should be pale yellow.
- Headaches and Dizziness: Dehydration is a frequent cause of headaches. Fluid loss can cause the brain to shrink temporarily, putting pressure on nerves and causing pain. It can also lead to dizziness or lightheadedness, especially when standing up quickly.
- Dry Skin and Reduced Elasticity: Skin is largely composed of water, and dehydration can make it look dry, dull, and flaky, and less elastic.
- Constipation: Water helps keep the digestive system running smoothly and keeps stool soft. Insufficient water intake makes stools harder and more difficult to pass.
- Mood Changes and Mental Fog: Dehydration can negatively affect your cognitive performance, leading to difficulty concentrating, confusion, irritability, and mood changes.
- Sugar Cravings: Sometimes, your body can confuse thirst signals with hunger, particularly cravings for sugary foods, as it tries to access energy stores.
Potential Complications of Severe Dehydration
If left untreated, severe dehydration can lead to serious complications including heat exhaustion, heatstroke, kidney stones, kidney failure, seizures due to electrolyte imbalance, and potentially life-threatening low blood volume shock.
