Excessive thirst can be a sign of diabetes while craving ice for warning that your body is deficient in iron.

Eating is not only to satisfy the emotional needs, stimulate the production of chemicals in the brain but also reflects what the body is missing. Here are 3 signs of appetite that you should keep in mind, according to Prevention.

Add water

Excessive thirst (not counting the time after exercise) is an early sign of diabetes, often accompanied by a lot of urination. Excess sugar accumulates in the blood, making the kidneys work harder to filter and absorb them. But sometimes the kidneys cannot guarantee the function of causing sweeteners to be released through the urine. That leads to disruption of normal hygiene habits and makes you constantly thirsty.

Add salt

Athletes sometimes lack salt due to perspiration and we rarely fall into the same situation by regularly absorbing more than the recommended salt level. In normal people, intense salt cravings can warn Addison's disease or chronic adrenal insufficiency . If left untreated, Addison's disease will cause blood pressure to drop to dangerous levels.

Add ice

Craving for things that have no nutritional value like ice, paper, clay . is called the pica phenomenon (craving for omnivores). Experts are not sure why this phenomenon exists, but many studies show a link between strange desires and iron deficiency. A scientific paper published in Medical Hypotheses recently suggested chewing ice increases blood flow to the brain, counteracting the body's stagnation when there is not enough iron.
