Anemia and Weight Loss
Anemia is a medical condition that can cause weight loss along with other symptoms. Although the underlying mechanisms of this relationship are not entirely clear, research suggests that anemia can affect appetite, metabolism, and energy expenditure, leading to weight loss.
Iron deficiency anemia, the most common type of anemia, is known to affect the body’s energy metabolism and lead to weight loss. A deficiency in iron decreases the body’s ability to utilize energy efficiently, resulting in increased fatigue and decreased physical activity levels. Additionally, iron is necessary for the production of hormones that play a key role in regulating metabolism and body weight. A deficiency in iron can disrupt this hormone balance, leading to weight loss.
Megaloblastic anemia and hemolytic anemia are other types of anemia that can cause weight loss. Megaloblastic anemia is caused by a deficiency in vitamin B12 or folate, and hemolytic anemia is caused by the premature destruction of red blood cells. These types of anemia can affect the body’s ability to absorb nutrients and produce energy, resulting in weight loss.
Research studies have investigated the relationship between anemia and weight loss. One study conducted in 2014 found that women with iron deficiency anemia had a significantly lower body mass index (BMI) compared to women without anemia. Another study conducted in 2018 found that individuals with megaloblastic anemia had a significantly lower body weight compared to healthy individuals.

Anemia and Weight Gain
Anemia is often associated with weight loss, but in some cases, it can also lead to weight gain. Although the underlying mechanisms are not fully understood, research suggests that anemia can affect energy levels, appetite, and metabolism, resulting in weight gain.
One way anemia can lead to weight gain is by decreasing physical activity levels. Fatigue and low energy levels associated with anemia can result in reduced physical activity, leading to weight gain. Anemia can also affect appetite by causing food aversions or changes in taste, leading to an increase in caloric intake and weight gain.
Certain types of anemia, such as hypothyroidism-associated anemia and anemia associated with chronic inflammation, can also lead to weight gain. Hypothyroidism is a condition that slows down the body’s metabolism, leading to weight gain. Chronic inflammation can also lead to weight gain by causing insulin resistance, disrupting glucose metabolism, and increasing fat storage.
Limited research has investigated the relationship between anemia and weight gain. However, one study found that women with iron-deficiency anemia had a higher waist circumference and body fat percentage than women without anemia.
While anemia may lead to weight gain in some cases, it is more commonly associated with weight loss.(B)
How to Manage Weight Changes Related to Anemia
Weight changes related to anemia can be managed by adopting healthy habits and seeking appropriate treatment. A balanced diet, physical activity, and adequate rest can help maintain a healthy weight. Treatment options for anemia vary depending on the underlying cause and may include supplements, medication, or transfusions.
Best Protein Powder for Weight Gain
Eating a nutrient-rich diet is crucial for preventing anemia and maintaining a healthy weight. Iron, vitamin B12 or folate are essential nutrients for healthy blood production. Foods like leafy greens, lean meats, and fortified cereals are excellent sources of these nutrients.
Physical activity can also help manage weight changes related to anemia. Exercise can improve energy levels, boost metabolism, and promote weight loss. Regular physical activity, such as brisk walking or cycling, can help maintain a healthy weight and improve overall health.(C)
Treatment Of Anemia
Treatment for anemia is necessary for managing weight changes. Iron supplements are commonly used to treat iron-deficiency anemia, while vitamin B12 injections are used to treat pernicious anemia. In some cases, blood transfusions or bone marrow transplants may be necessary.(D)
When To See a Doctor
It is essential to seek medical advice if you experience unexplained weight changes. Your healthcare provider can diagnose and treat anemia, provide guidance on maintaining a healthy weight, and monitor any changes in weight over time.
Conclusion
In summary, managing weight changes related to anemia requires a holistic approach that includes a healthy diet, physical activity, and adequate rest. Treatment for anemia is also critical for managing weight changes. Seeking medical advice and monitoring weight changes over time is essential for maintaining a healthy weight and managing anemia effectively.
FAQs
Do Iron Tablets Cause Weight Gain?
Does Low Hemoglobin Increase Weight?
Low hemoglobin levels do not directly cause weight gain. Hemoglobin is a protein that carries oxygen in the body. When hemoglobin levels are low, it can lead to a condition called anemia. Anemia can cause symptoms like fatigue, weakness, and shortness of breath, which can make a person less active and potentially lead to weight gain.
However, weight gain due to anemia is not caused directly by low hemoglobin levels themselves, but by the impact that anemia has on a person’s energy levels and physical activity. If you suspect you have anemia or other health concerns, it’s important to speak with a healthcare provider.
How To Gain Weight With Anemia?
To gain weight when you have anemia, it’s crucial to first focus on treating the anemia itself. This typically involves increasing your iron intake through diet or supplements, as directed by your healthcare provider.
Once your anemia is under control, you can start working on gaining weight in a healthy way. Here are some strategies to consider:
- Eat small, frequent meals throughout the day instead of a few large meals.
- Choose foods that are nutrient-dense and high in calories, such as lean protein, whole grains, fruits, vegetables, and healthy fats.
- Drink calorie-dense beverages like smoothies or milkshakes.
- Incorporate healthy snacks into your diet, such as nuts, seeds, and dried fruits.
- Work with a registered dietitian to create a personalized nutrition plan that meets your specific needs.
It’s important to remember that healthy weight gain is a gradual process and should be approached in a sustainable manner. Consult with a healthcare provider before making significant changes to your diet or lifestyle.
What Cancer Causes Anemia and Weight Loss?
Anemia and weight loss can be caused by several types of cancer. The most common types of cancer that can lead to these symptoms are blood cancers like leukemia, lymphoma, and multiple myeloma, as well as gastrointestinal (GI) cancers such as colon, stomach, and pancreatic cancer.
Lung cancer can also cause anemia and weight loss due to the cancer’s impact on metabolism and nutrient absorption. Other cancers, including ovarian, kidney, and liver cancer, can also cause anemia and weight loss.
It’s important to note that anemia and weight loss can have many potential causes, and a healthcare provider should be consulted for an accurate diagnosis and treatment plan. Early detection and treatment of cancer can improve outcomes and quality of life.
