A person with severe anemia often looks pale (washed-out skin, pale gums/eyelids/nail beds), fatigued, and may have cold hands/feet, brittle nails, hair loss, a sore/swollen tongue, and a fast heartbeat or shortness of breath, especially with activity, due to low oxygen. They might also experience dizziness, headaches, irritability, and unusual cravings for non-food items (pica) as their body struggles to get oxygen.
Symptoms of iron-deficiency anemia may include: Being pale or having yellow "sallow" skin. Unexplained fatigue or lack of energy. Shortness of breath or chest pain, especially with activity.
If left untreated, anemia can lead to various health issues, including severe tiredness that limits daily activities, complications during pregnancy, or heart problems. Early symptoms of anemia include: Feeling tired or weak. Loss of appetite.
People with digestive problems may have low iron levels alongside diarrhea and other digestive symptoms. However, having low iron is probably not the cause of the diarrhea. Rather, the digestive problem at the root of the diarrhea may be causing low iron.
Anemia causes a pale, washed-out look due to low hemoglobin which is termed pallor. Dullness and dark circles are caused due to reduced oxygen impact on the skin. Anemia affects hydration, leaving skin dry and rough. Pallor is noticeable in areas like the face, lips, eyelids, under eye, and nail beds.
Pale or yellow skin
You look in the mirror and feel like you're a bit paler than usual. Iron deficiency may cause you to appear pale, especially on your face, lips and inner eyelids.
Grading of anemia, according to the National Cancer Institute, is as follows: Mild: Hemoglobin 10.0 g/dL to lower limit of normal. Moderate: Hemoglobin 8.0 to 10.0 g/dL. Severe: Hemoglobin 6.5 to 7.9 g/dL[1]
Warning signs of anemia you shouldn't ignore
Weakness. Dizziness. Shortness of breath. Irregular heartbeat.
Symptoms of the conditions associated with bleeding that cause iron deficiency anemia include: Dark, tar-colored stools or blood in the stool. Heavy menstrual bleeding. Pain in the upper belly (from ulcers)
The European consensus on the diagnosis and management of iron deficiency and anaemia in inflammatory bowel disease (ECCO Guidelines), recommend iron supplementation, preferably intravenous (IV), for patients with ferritin levels <30 ng/mL or <100 ng/mL and TSAT <20%15.
Anemia can lead to a rapid or irregular heartbeat, called arrhythmia. With anemia, the heart must pump more blood to make up for too little oxygen in the blood. This can lead to an enlarged heart or heart failure. Death.
Anemia due to iron deficiency is a highly prevalent medical condition in women and children. Iron deficiency presents with fatigue, low mood, anxiety, restlessness, palpitations, and headache. Poor nutritional intake can be the reason of iron deficiency in underprivileged populations.
Types of Cancer that Cause Anemia
Anemia occurs when cells and organs do not receive enough blood to function properly, resulting in symptoms of fatigue, weakness, shortness of breath, pale skin, and jaundice, as well as impaired brain function. Severe anemia can result in heart failure, fainting, and death.
Recent research suggests that GLP-1 receptor agonists—medications like Ozempic, Wegovy, and Zepbound—may increase the risk of iron deficiency anemia. With millions of Americans now using these medications, understanding this potential connection has never been more important.
Hematologists are medical specialists in treating blood and bone marrow disorders. Their expertise encompasses diagnosing, treating, and managing a broad spectrum of hematologic conditions, including anemia.
Iron deficiency is not just a blood disorder; it actually affects the brain and body directly and often disrupts sleep. Recognizing its relationship to RLS, insomnia, and restlessness at night in kids and the elderly can lead to earlier diagnosis, better treatment, and better nights of sleep.
For example, “a man who is iron deficient needs evaluation for their GI tract and, in general, they need a colonoscopy and often esophagogastroduodenoscopy, or EGD, as well.”
Fatigue, headache and irritability are common symptoms of iron deficiency, but there are other symptoms too. You may experience one or more of these symptoms at the same time.
Anemia may increase your risk of a heart attack. Call 911 if you have the following symptoms: Chest pain. Shortness of breath or trouble breathing.
Iron deficiency anemia in early life is related to altered behavioral and neural development. Studies in human infants suggest that this is an irreversible effect that may be related to changes in chemistry of neurotransmitters, organization and morphology of neuronal networks, and neurobiology of myelination.
Congenital Dyserythropoietic Anemia (CDA)
CDA is a group of inherited anemias that reduce the number of healthy red blood cells in the body. All CDAs are passed down through families. There are four types of CDA: types 1, 2, 3, and 4. Type 2 is the most common and type 4 is the rarest and most severe.
