Understanding Low MCHC: Causes, Symptoms, and Treatment Options


When it comes to understanding blood test results, medical jargon can be confusing. One such term you may come across is MCHC, which stands for Mean Corpuscular Hemoglobin Concentration. MCHC is a measurement that assesses the concentration of hemoglobin in your red blood cells. In this article, we will focus on low MCHC, exploring its causes, symptoms, and treatment options.

Understanding MCHC

Mean Corpuscular Hemoglobin Concentration (MCHC) is a crucial metric that helps evaluate the amount of hemoglobin present in each red blood cell. Hemoglobin carries oxygen throughout the body, ensuring proper cellular function. MCHC is measured as part of a complete blood count (CBC) and is expressed as a percentage.

Causes of Low MCHC

Low MCHC levels can indicate various underlying health conditions. Some common causes of low MCHC include:

  1. Iron deficiency anemia: Insufficient iron levels can lead to low MCHC, as hemoglobin synthesis is impaired.
  2. Thalassemia: A genetic blood disorder that affects hemoglobin production, causing low MCHC levels.
  3. Chronic diseases: Conditions such as chronic kidney disease or liver disease can contribute to low MCHC.
  4. Hemolytic anemia: When red blood cells are destroyed faster than they can be produced, it can result in low MCHC.
  5. Nutritional deficiencies: Inadequate intake of nutrients like iron, vitamin B12, or folate can lead to low MCHC.

Symptoms and Diagnosis of Low MCHC

Low MCHC levels may manifest through various symptoms, including:

  • Fatigue and weakness
  • Pale skin and nail beds
  • Shortness of breath
  • Dizziness or lightheadedness

To diagnose low MCHC, a comprehensive blood test, including a CBC, is conducted. Additionally, your doctor may review your medical history, perform a physical examination, and order additional tests to identify the underlying cause.

Treatment Options for Low MCHC

Treating low MCHC involves addressing the underlying cause. Depending on the diagnosis, treatment options may include:

  1. Iron supplementation: In cases of iron deficiency anemia, iron supplements may be prescribed to increase MCHC levels.
  2. Blood transfusions: For severe cases, blood transfusions may be necessary to restore normal MCHC levels.
  3. Treating underlying conditions: If a chronic disease or genetic disorder is responsible for low MCHC, managing and treating the underlying condition can help improve MCHC levels.
  4. Dietary modifications: Adjusting your diet to include iron-rich foods and other nutrients essential for red blood cell production can aid in increasing MCHC levels.

Lifestyle Changes for Improving MCHC

In addition to medical interventions, certain lifestyle changes can support the improvement of MCHC levels. Consider the following:

  • Quitting smoking: Smoking can hinder red blood cell function and decrease

the overall MCHC levels. Quitting smoking can have a positive impact on your blood cell health.

  • Regular exercise: Engaging in regular physical activity can promote healthy blood circulation, which in turn can help improve MCHC levels.
  • Stress management: Chronic stress can negatively affect various aspects of your health, including your blood cell production. Implement stress management techniques such as meditation, yoga, or engaging in hobbies to reduce stress levels.

Diet Recommendations for Low MCHC

A well-balanced diet plays a crucial role in maintaining optimal MCHC levels. Consider the following dietary recommendations:

  1. Iron-rich foods: Include iron-rich foods such as lean meats, poultry, fish, legumes, dark leafy greens, and fortified cereals in your diet. These foods can help increase iron levels, supporting MCHC production.
  2. Vitamin B12 sources: Foods like eggs, dairy products, fortified plant-based milk, and seafood are excellent sources of vitamin B12. Adequate vitamin B12 levels are necessary for healthy red blood cell formation.
  3. Folate-rich foods: Consume foods rich in folate, such as leafy greens, citrus fruits, beans, and fortified grains. Folate is essential for the production of healthy red blood cells.
  4. Stay hydrated: Drinking an adequate amount of water helps maintain proper blood volume and circulation, which is crucial for optimal MCHC levels.

Supplements for Increasing MCHC

In some cases, supplements may be recommended to improve MCHC levels. However, it’s essential to consult with your healthcare provider before starting any supplements. They may suggest:

  • Iron supplements: Iron supplementation can be beneficial in cases of iron deficiency anemia, helping to increase MCHC levels.
  • Vitamin B12 supplements: If low MCHC is due to vitamin B12 deficiency, your doctor may recommend vitamin B12 supplements to address the deficiency and improve MCHC.

Managing Underlying Conditions

When low MCHC is caused by an underlying health condition, managing that condition is crucial. For example:

  • If chronic kidney disease is contributing to low MCHC, following your healthcare provider’s recommendations for kidney disease management can help improve MCHC levels.
  • If you have thalassemia, working closely with a hematologist and following their prescribed treatment plan is essential for maintaining optimal MCHC levels.

Complications and Risks

Ignoring low MCHC levels or failing to address the underlying causes can lead to potential complications. Some risks associated with untreated or poorly managed low MCHC include:

  • Worsening fatigue and weakness
  • Increased susceptibility to infections
  • Impaired cognitive function and concentration
  • Difficulty in carrying out daily activities

Therefore, it’s crucial to seek medical attention and follow the recommended treatment plan to prevent these complications.

Preventive Measures

While some causes of low MCHC are unavoidable, there are preventive measures you can take to maintain optimal MCHC levels:

  • Adopt a balanced diet rich in essential nutrients, especially iron, vitamin B12, and folate.
  • Regularly exercise and maintain a healthy lifestyle.
  • Avoid smoking and limit alcohol consumption.
  • Attend regular check-ups and screenings to identify any underlying conditions early on.

By incorporating these preventive measures into your life, you can reduce the risk of developing low MCHC.


In conclusion, low MCHC can be an indicator of various underlying health conditions. Understanding the causes, symptoms, and treatment options is crucial for managing this condition effectively. By working closely with healthcare professionals, making necessary lifestyle changes, and following the recommended treatment plan, you can improve your MCHC levels and maintain overall blood health.
