Anemia in Women Symptoms and Causes of Iron Deficiency

Iron deficiency and anemia are common health challenges, especially for people who menstruate. Recognizing the signs like fatigue or heart palpitations can help you seek timely treatment and regain your energy. While boosting iron levels takes time, early intervention can make all the difference.

Why Is Iron Important?

Iron is a critical mineral in your blood that supports healthy tissue, muscles, and cell function. It’s also an essential component of hemoglobin, the protein that carries oxygen from your lungs to the rest of your body, according to the National Institutes of Health (NIH).

For people who menstruate, the recommended dietary allowance (RDA) of iron is 18 milligrams daily double that of men. Pregnant individuals need even more: 27 milligrams per day, to support increased blood volume and fetal development.

Causes of Iron Deficiency

Iron deficiency occurs when your body doesn’t have enough iron to produce adequate hemoglobin. Common causes include:

• Heavy Menstrual Periods: Blood loss during menstruation depletes iron levels.

• Pregnancy: Increased blood volume and fetal development require more iron.

• Poor Diet: Low intake of iron-rich foods, especially for vegetarians and vegans.

• Chronic Conditions: Diseases like celiac or Crohn’s can hinder iron absorption.

• Economic and Nutritional Factors: Minority women face higher risks due to systemic disparities, per the CDC.

Symptoms of Iron Deficiency

1. Fatigue and Sleepiness
Feeling persistently tired or struggling to stay awake, even after sufficient sleep, is one of the most common symptoms. This can manifest as both physical and mental fatigue, affecting athletic performance and focus.

2. Heart Palpitations
A resting heart rate above 100 beats per minute could indicate iron deficiency. Symptoms might feel like a racing or irregular heartbeat.

3. Frequent Infections
Iron deficiency weakens the immune system, making you more susceptible to illnesses.

4. Other Symptoms:

• Dizziness or headaches

• Shortness of breath

• Restless leg syndrome

• A pounding or "whooshing" sound in your ear

Visible Signs of Low Iron

Look for these physical indicators:

• Pale Skin: Especially noticeable inside the lower eyelids.

• Brittle Nails: Fragile or spoon-shaped nails.

• Swollen Tongue or Mouth Sores: Cracks at the corners of the mouth may also appear.

Diagnosing and Treating Iron Deficiency

Iron deficiency is diagnosed through blood tests measuring hemoglobin and ferritin levels. Treatment options include:

1. Eating Iron-Rich Foods
Incorporate these into your diet:

• Heme Iron: Found in meat, poultry, and fish; easily absorbed.

• Non-Heme Iron: Found in beans, spinach, fortified cereals, and dried fruits. Pair with vitamin C-rich foods (like citrus or broccoli) to enhance absorption.

2. Iron Supplements
Iron pills are a common treatment, but they take three to six months to normalize levels. Work with a healthcare provider to avoid side effects like constipation or upset stomach.

3. Iron Infusions
For severe deficiency, intravenous (IV) iron can rapidly restore levels in one or a few sessions.

Coping With Sleepiness

Because recovery takes time, managing fatigue is essential:

• Prioritize Sleep: Aim for 7–9 hours nightly and maintain a consistent bedtime.

• Take Short Naps: Recharge with 10-minute naps during the day.

• Limit Alcohol and Nicotine: Both disrupt sleep and worsen tiredness.

Prevention and Awareness

Iron deficiency is preventable with a balanced diet and awareness of risk factors. Routine screenings for pregnant individuals and those with heavy periods can help catch deficiencies early.

Recognizing and addressing iron deficiency is a step toward better energy, focus, and overall health. If you’re experiencing symptoms, consult a healthcare provider for proper testing and treatment options.
