Heart and lung problems Adults with severe anaemia may be at risk of developing complications that affect their heart or lungs. For example, you may develop tachycardia, which is an abnormally fast heartbeat, or heart failure, where the heart fails to pump enough blood around your body at the right pressure.
If left untreated, iron-deficiency anemia can cause serious health problems. Having too little oxygen in the body can damage organs. With anemia, the heart must work harder to make up for the lack of red blood cells or hemoglobin. This extra work can harm the heart.
Left untreated, however, iron-deficiency anemia can make you feel tired and weak. You may notice pale skin and cold hands and feet. Iron-deficiency anemia can also cause you to feel dizzy or lightheaded. Occasionally, it can cause chest pain, a fast heartbeat and shortness of breath.
Untreated anemia can cause a rapid or irregular heartbeat. It also puts a lot of stress on your heart. Anemia lowers your red blood cell count. When you don't have enough red blood cells, your heart has to pump a lot more blood to make sure that enough oxygen gets to all your organs.
If you have iron deficiency anemia, it can take three to six months to get your iron levels back to normal. However, different people may react to treatment differently. Some start seeing the results in just a few weeks, while others may not achieve the desired levels for months.
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.
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.
Treatment for iron-deficiency anemia will depend on its cause and severity. Treatments may include dietary changes and supplements, medicines, and surgery. Severe iron-deficiency anemia may require a blood transfusion, iron injections, or intravenous (IV) iron therapy. Treatment may need to be done in a hospital.
If you think you may have severe anemia, it is essential that you call your physician, go to the emergency room for evaluation, or call 911 to get help. One treatment that may help those with severe anemia could be hyperbaric oxygen therapy (HBOT).
Living with anemia
Following treatment, most people go on to live normal, healthy lives. However, anemia can have lasting, or life-threatening, effects. These are more common if the condition is chronic, severe, or left untreated.
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.
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.
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.
Specifically, iron plays an important role in how your body makes the neurotransmitters called serotonin, dopamine and norepinephrine – all of them important in mental health. Research suggests a connection between low iron levels and symptoms of depression, anxiety, and schizophrenia, Levin and Gattari write.
Sometimes iron deficiency will present as anxiety, depression, irritability, and even poor concentration and general restlessness.
Low iron levels are commonly found in individuals who have fibromyalgia, restless leg syndrome, and chronic muscle pain. The American Society of Hematology has suggested that people with iron deficiencies may experience trigger point pain in their muscles that results from a lack of oxygen being delivered to them.
The last stage is iron deficiency anemia. It is characterized by a low hemoglobin concentration with small (microcytic), pale (hypochromic) RBCs. Symptoms include fatigue upon exertion, weakness, headaches, apathy, pallor, poor resistance to cold temperatures, low physical work capacity, and poor immune function.
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.
To treat iron deficiency anemia, your doctor may recommend that you take iron supplements. Your doctor will also treat the underlying cause of your iron deficiency, if necessary.
If you have anemia, your body does not get enough oxygen-rich blood. The lack of oxygen can make you feel tired or weak. You may also have shortness of breath, dizziness, headaches, or an irregular heartbeat.
"If you actually ask women who have iron deficiency what their symptoms are, fatigue and tiredness is there but right at the top of the list is brain fog and that's what women described — it's the inability to think clearly," says Professor Toby Richards.
Our study shows a significantl positive correlation between sleep quality and iron supplement intake (p <0.17). A deficiency in iron has an effect on sleep quality, quantity and timing; iron also affects the modulation of REM sleep.
One way iron deficiency anaemia can impact your weight is through thyroid function and metabolism [10]. Your thyroid hormone and metabolism are responsible for helping your body burn calories, so naturally, if they are underactive, this can lead to weight gain.
While there's little scientific evidence backing this claim up, weight gain from iron pills does happen 6. One study found that individuals with iron deficiency anemia complained of weight gain during their treatment, even though oral preparations of iron aren't known to cause weight gain as a side effect.
