Dehydration occurs when your body loses more fluids than it takes in, and it can affect physical and mental performance. It may develop slowly or suddenly, depending on the cause.
Common Signs of Dehydration
1. Thirst
Feeling unusually thirsty is often the first sign your body needs more fluids.
2. Dry Mouth and Lips
A sticky or dry feeling in your mouth and cracked lips can signal dehydration.
3. Dark Yellow Urine
Healthy urine is light yellow. Dark yellow or amber-colored urine indicates your body lacks water.
4. Reduced Urine Output
Urinating less frequently (fewer than 3–4 times per day) may be a sign of dehydration.
5. Fatigue or Weakness
Low fluid levels can reduce energy and cause tiredness or dizziness.
6. Headache
Dehydration can cause mild to severe headaches or migraines.
7. Dizziness or Lightheadedness
Especially when standing up quickly, this may mean blood volume is too low.
8. Dry Skin
Skin may lose its elasticity and look dull or flaky.
9. Rapid Heartbeat or Breathing
As dehydration worsens, your heart rate and breathing can speed up.
10. Confusion or Irritability
In severe cases, dehydration can affect mental clarity and mood.
