Without enough iron, your body can't produce enough of a substance in red blood cells that enables them to carry oxygen (hemoglobin). As a result, iron deficiency anemia may leave you tired and short of breath.
Extreme fatigue and exhaustion “Fatigue is one of the most common signs of iron deficiency because it means your body is having trouble carrying the oxygen to your cells so it's affecting your energy levels,” Thayer says. People lacking enough iron in their blood often feel sluggish, weak, and unable to focus.
Having an iron-deficiency may not cause insomnia or sleep problems but it can make you feel exhausted and overtired, which in turn may hinder your efforts to fall asleep in the first place!
Severe iron deficiency anaemia may increase your risk of developing complications that affect the heart or lungs, such as an abnormally fast heartbeat (tachycardia) or heart failure, where your heart is unable to pump enough blood around your body at the right pressure.
Your body relies on iron to make hemoglobin, so when iron is low, you can become anemic. Your cells don't receive enough oxygen, and you feel tired. “The most frequent symptom of iron-deficiency anemia is fatigue,” says Kathryn Boling, MD, a family doctor at Mercy Medical Center in Baltimore.
Iron-Rich Foods
Heme iron is found in meat, fish and poultry. It is the form of iron that is most readily absorbed by your body. You absorb up to 30 percent of the heme iron that you consume. Eating meat generally boosts your iron levels far more than eating non-heme iron.
Iron-rich drinks include apple juice, apricot nectar, beef broth, beet juice, cocoa using natural cocoa powder, “green” smoothies, orange juice, pea protein smoothies, prune juice, tomato juice, and spinach juice.
Common causes of iron deficiency include not getting enough iron in your diet, chronic blood loss, pregnancy and vigorous exercise. Some people become iron deficient if they are unable to absorb iron. Iron deficiency can be treated by adding iron-rich foods to the diet.
You may also find that low iron causes weight gain. There are a couple of reasons for this; firstly, your energy levels are low and so your exercise levels reduce; secondly, iron is essential for thyroid function, and an underactive thyroid will lead to weight gain.
Eye symptoms of low iron can include a pale coloring of the inside of the lower eyelids. In moderate or severe cases of iron deficiency anemia, the inside layer of the lower eyelid is very pale pink or yellow instead of red. Rather than low iron, one common cause of blurry vision is dry eye.
A large 2020 study in BMC Psychiatry found that people with iron deficiency anemia had a significantly higher incidence and risk of anxiety disorders, depression, sleep disorder, and psychotic disorders.
Several treatments can be used to treat anemia. Iron supplements, also called iron pills or oral iron, help increase the iron in your body. This is the most common treatment for iron-deficiency anemia. It often takes three to six months to restore your iron levels.
With treatment, most people recover from iron-deficiency anemia in 2 to 3 months. You may need to take iron supplements for several months longer, though, to build up your reserves of iron.
It may take one to four weeks (after you start your iron supplement) before you start to feel better. Continue to watch your symptoms and take note of side effects. If you have any questions or concerns, talk to your healthcare provider.
Iron deficiency anemia and depression
According to a 2020 study , iron deficiency anemia can increase a person's risk of depression. Iron deficiency can cause low levels of serotonin, an important neurotransmitter and mood stabilizer.
The range of normal ferritin in most laboratories is 30 ng/mL to 300 ng/mL, and the mean is 49 ng/mL in women. The National Health and Nutrition Examination Survey describes iron deficiency in women as a low concentration of ferritin (<12 ng/mL). Diagnosis prompts consideration of the cause of IDA (usually, bleeding).
In many cases, mild iron deficiency anemia comes on so gradually that you may not even know you're anemic. Symptoms of mild anemia are subtle and include feeling grumpy, weak or tired more often than usual and getting headaches or perhaps having problems concentrating.
– It usually takes 2 to 3 weeks of taking regular iron supplements before your symptoms start to improve. – You may need to keep taking iron for several months to build up your iron reserves and keep your anemia from returning. Take your pills for as long as your doctor recommends, even if your symptoms have improved.
What's the difference between being anemic and being iron deficient? If you're iron deficient, it simply means your body has a low iron count. Iron deficiency is the most common nutritional deficiency worldwide. In fact, it is estimated that up to 25% of the world's population suffers from low iron.
If you suspect you might have an anemic disorder, check yourself for the following symptoms and call your doctor for further advice. A sudden lack of energy and chronic fatigue are warning signs that you might be lacking enough iron.
Most of the time fatigue can be traced to one or more lifestyle issues, such as poor sleep habits or lack of exercise. Fatigue can be caused by a medicine or linked to depression. Sometimes fatigue is a symptom of an illness that needs treatment.
Iron is a mineral that the body needs for growth and development. Your body uses iron to make hemoglobin, a protein in red blood cells that carries oxygen from the lungs to all parts of the body, and myoglobin, a protein that provides oxygen to muscles. Your body also needs iron to make some hormones.
Take vitamin C with your source of iron.
Vitamin C increases absorption of both heme and non-heme iron absorption. Four ounces (1/2 cup) of orange juice is enough to increase iron absorption. Other sources of vitamin C include citrus fruit, fresh bell peppers, strawberries, cantaloupe, and fresh broccoli.
