The worst symptoms of low iron, often stemming from iron-deficiency anemia, significantly impact daily life and can be serious if left untreated. These include:
Severe Fatigue and Weakness
Perhaps the most prevalent and debilitating symptom is extreme tiredness and weakness. This isn't just feeling a little sluggish; it's a profound lack of energy that interferes with daily activities and responsibilities. [Reference: Left untreated, however, iron-deficiency anemia can make you feel tired and weak.]
Shortness of Breath and Heart Problems
Low iron levels can lead to shortness of breath, even during minimal exertion. In severe cases, it can also cause chest pain, a rapid heartbeat (tachycardia), and other heart-related complications. This is because insufficient iron reduces the blood's ability to carry oxygen throughout the body, impacting the heart's function.

Pale Skin and Other Physical Manifestations
Pale skin is a common indicator, often accompanied by cold hands and feet. Other physical symptoms include brittle nails and sores in the corners of the mouth. In some instances, severe anemia may manifest as yellowish skin (sallow).

Neurological and Mental Health Impacts
While less commonly discussed, low iron can negatively impact mental health, potentially worsening symptoms of depression, anxiety, and even schizophrenia. This highlights the importance of considering iron levels when evaluating mental health conditions. [Reference: Research suggests a connection between low iron levels and symptoms of depression, anxiety, and schizophrenia, Levin and Gattari write.]
It's crucial to remember that these are severe symptoms. If you experience any of these, especially in combination, consult a doctor immediately for proper diagnosis and treatment.
