Symptoms, conditions and causes

Why am I so thirsty?

Increased thirst is a condition where you are more thirsty than normally. It usually happens with frequent urination. This can create a problem as you can lose your electrolytes fast.

Cause #1: Diabetes / insulin resistance

If you have insulin resistance or diabetes either can cause excessive thirst. This is because water follows blood sugar. Having these conditions you lose your water fast and the loss signals to your brain, causing you to want to drink more water.


  • Drink when you’re thirsty

  • Avoid refined carbs and sugar

  • Avoid snacking

  • Do the Healthy Keto® diet

  • Do an intermittent fasting plan

  • If you have diabetes and the above remedies don’t work, get checked for diabetes insipidus.

Cause #2: Potassium/Sodium imbalance

Having a balanced ratio of sodium-potassium is needed for proper hydration in the body. Normally the ratio should be about 4,700 mg of potassium to 1,000 mg of sodium per day, a 4.7 to 1 ratio. If you have high amounts of sodium, this can create potassium deficiency symptoms; and it applies the opposite way too.


  • You may have to reduce/increase the amounts of either sodium or potassium to get a perfect balance and not feel too thirsty anymore

  • Consume more potassium if needed: raw vegetables

  • Consume more sodium if needed: Himalayan sea salt

Cause #4: Too much calcium

When you consume too much calcium or you have too much calcium in the body this is the condition called hypercalcemia. One of its side effects is frequent urination and excessive thirst.


  • Reduce/avoid consumption of calcium

Cause #5: Certain drugs and medicines

If you consume certain drugs, psych drugs, diuretics or even steroids they can cause your body to lose fluid or you may have excessive thirst as one of their side effects.


  • If you suspect that excessive thirst is coming from the consumption of drugs, consult with your doctor about lowering your dosage or substituting another medicine.

Other causes:

  • Habit

  • Hyperaldosteronism

  • Alcohol

  • Cancer (can cause too much calcium)

  • Hyperparathyroidism (can cause too much calcium)

  • Lithium (can cause too much calcium)

  • Huge amounts of vitamin D (can cause too much calcium)
