4 strange signs when the body lacks iron

Iron deficiency is a fairly common health problem and anyone can get it. People with an unhealthy diet, pregnant women and children are at high risk of iron deficiency. , according to health site Medical News Today (UK).

Iron deficiency can cause headaches because the amount of oxygen to the brain decreases, causing blood vessels in the brain to swell.

Constant fatigue is a common sign of iron deficiency. Iron deficiency can lead to anemia, which can leave you feeling so tired that you can’t complete your daily tasks.

In addition, iron deficiency also leads to the following symptoms:

Arrhythmia

Long-term iron deficiency will cause a decrease in the number of red blood cells that carry oxygen in the blood. As a result, the heart must pump more blood to compensate for the low oxygen level. The heart will therefore beat faster and lead to heart rhythm disturbances. . This condition, if prolonged, can cause heart failure or an enlarged heart.

Severe headache

Iron deficiency also causes the brain to receive less oxygen. As a result, blood vessels in the brain swell and cause headaches. Many people even complain of dizziness and lightheadedness.

In addition, experts say that headaches due to iron deficiency are also partly caused by changes in dopamine and estrogen hormone levels in the body. The pain usually appears on one side of the head and may be accompanied by nausea, vomiting, and impaired vision.

Mouth ulcers

Iron deficiency can cause anemia and lead to another unpleasant condition called mouth ulcers. These ulcers can be painful and even bleed if they become large. Other symptoms that appear in the mouth include a swollen, inflamed, pale, strangely smooth tongue, dry mouth, and red cracks at the corners of the mouth.

Tinnitus

Long-term iron deficiency can also cause another strange symptom: tinnitus. Because when you have anemia, your heart will work harder to compensate for the lack of oxygen. More blood will be pumped between your heart and your brain. This process causes more blood to flow through your middle ear, causing tinnitus, according to Medical News Today.
