Dyspnea due to iron deficiency anemia?


I am a female, 162 cm tall and weigh 47 kg.
Recently, I have been experiencing difficulty breathing while sleeping, needing to take deep breaths to feel like I'm getting enough air, which has caused me insomnia.
I visited a thoracic surgeon and had an X-ray, but the doctor said everything was normal.
Later, I went to a family medicine clinic where I was diagnosed with iron deficiency anemia, and I also have a habit of chewing ice, which is related to the anemia.
I felt better for a while and my breathing difficulties improved, but in the past few days, I have started to experience breathing difficulties again, needing to take deep breaths to get air, especially when trying to sleep.
This has made it hard for me to sleep, and I feel dizzy from the lack of air.
Previously, I only experienced breathing difficulties at night, but now I am also having trouble during the day, requiring deep breaths to get enough air.
I have also been diagnosed with scoliosis.
Should I go back to the hospital for another check-up?

Dear Anonymous: This can be divided into two parts: one is true dyspnea, which can be evaluated through pulmonary function tests, or anemia leading to insufficient oxygen-carrying hemoglobin (though this is unlikely).
The second part is psychogenic, which is more related to emotions.
Changhua Hospital cares about you.

More Info


Breathing difficulties can be a concerning symptom, especially when they interfere with sleep and daily activities. In your case, it seems that you are experiencing episodes of shortness of breath, particularly at night, which has been linked to iron deficiency anemia. Let's explore the relationship between these symptoms and the potential underlying causes.

Iron deficiency anemia is a common condition, especially among women, due to factors such as menstruation, pregnancy, and dietary insufficiencies. When the body lacks sufficient iron, it cannot produce enough hemoglobin, the protein in red blood cells that carries oxygen. This can lead to symptoms such as fatigue, weakness, and in some cases, shortness of breath. The body may struggle to deliver adequate oxygen to tissues, which can manifest as difficulty breathing, particularly during physical exertion or when lying down.

Your mention of craving ice (a condition known as pagophagia) is often associated with iron deficiency. This craving can be a sign that your body is signaling a need for iron, and it’s important to address this deficiency to alleviate symptoms. Treatment typically involves dietary changes to include more iron-rich foods (such as red meat, beans, lentils, and fortified cereals) and possibly iron supplements, as advised by your healthcare provider.

The fact that your breathing difficulties have recurred suggests that there may be other factors at play. While your chest X-ray was normal, it’s essential to consider other potential causes of your symptoms. For instance, anxiety can lead to hyperventilation, which may cause feelings of breathlessness and dizziness. If you find that your breathing difficulties are accompanied by feelings of panic or anxiety, it may be beneficial to explore stress management techniques or speak with a mental health professional.

Additionally, you mentioned having scoliosis (curvature of the spine), which could potentially impact your respiratory function. Depending on the severity of the curvature, it can affect lung capacity and the mechanics of breathing. If your scoliosis is significant, it may be worth discussing with a specialist to see if it could be contributing to your symptoms.

Given that your symptoms have returned and are affecting your quality of life, it would be prudent to follow up with your healthcare provider. They may recommend further evaluations, such as pulmonary function tests, to assess your lung capacity and function. This can help determine if there are any underlying respiratory issues that need to be addressed.

In summary, your breathing difficulties could be related to iron deficiency anemia, anxiety, or structural issues from scoliosis. It’s important to address the iron deficiency through dietary changes and possibly supplementation, while also considering other potential causes of your symptoms. A follow-up visit to your healthcare provider is advisable to ensure a comprehensive evaluation and to discuss the best course of action for your health. Remember, it’s crucial to listen to your body and seek help when symptoms persist or worsen.
