Most common symptoms of high mch :

Shortness of breath

Shortness of Breath

High MCH values make you very tired and you may also become breathless. Shortness of breath, also known as dyspnea is a feeling of not being able to breathe well enough.

Dyspnea is a normal symptom of heavy exertion but becomes pathological if it occurs in unexpected situations, like when your MCH levels are high. High MCH that develops gradually usually presents with exertional dyspnea, fatigue and weakness. High MCH is often a cause of dyspnea.

Headaches are also a symptom of dyspnea in patients suffering from abnormal levels of MCH.

Weakness is a symptom of a number of different conditions and high MCH is one of them.

Weakness is a lack of physical or muscle strength and the feeling that extra effort is required to move your arms, legs, or other muscles. General weakness often occurs after you have done too much activity at one time, such as by taking an extra-long hike. You may feel weak and tired, or your muscles may be sore.

But weakness may be caused by another health problem such as high MCH.

Fatigue is a feeling of tiredness. It may be sudden or gradual in onset. A person with fatigue may find it physically hard to do the things they usually do, such as climbing the stairs. However, it may be a symptom of a medical condition if it is prolonged, severe, progressive, or occurs without provocation.

Fatigue is one of the symptoms of High MCH levels. A person can have fatigue and weakness when he or she has a higher MCH than is normal. While it's normal to feel tired after a long day at work, when you have high MCH because of B-12 or folate deficiencies, you feel weary after shorter and shorter periods of exertion

Headache is frequently reported as one of the neurological manifestations of high MCH. An MCH value calculated above 32 pg is considered high MCH. This means that there is a larger amount of hemoglobin present per red blood cell.

High MCH value can often be caused by anemia due to a deficiency of B vitamins, particularly B-12 and folate. Both of these vitamins are required by your body in order to make red blood cells. When MCH is high in blood, you may experience headaches.

Severe vitamin B12 deficiency is corrected with frequent intramuscular injections of large doses of the vitamin, followed by maintenance doses of injections or oral dosing at longer intervals.

Dizziness or lightheadedness


High MCH may cause you to feel fatigued and lightheaded and to experience headaches and vision changes.

Dizziness is a symptom that often applies to a variety of sensations including lightheadedness and vertigo. Dizziness can also refer to disequilibrium or a non-specific feeling such as giddiness or foolishness.

Stomach pain

Stomach pain

Stomach ache is a symptom associated with both non-serious and serious medical issues. The most frequent reasons for abdominal pain are gastroenteritis (13%), irritable bowel syndrome (8%), urinary tract problems (5%), inflammation of the stomach (5%) and constipation.

But high mch levels may also be a cause of abdominal pain. Seek prompt medical care if your abdomen becomes swollen or distended.

Joint pain

Joint Pain

Joint pain is one of the most common symptoms of high mch. High MCH value can often be caused by anemia due to a deficiency of B vitamins, particularly B-12 and folate.

Vitamin B12 is a water-soluble vitamin involved in metabolism. Vitamin B12 deficiency can potentially cause severe and irreversible damage, especially to the brain and nervous system.

Vitamin B12 deficiency is most commonly caused by low intake, but can also result from malabsorption, certain intestinal disorders, low presence of binding proteins, or use of certain medications. Vegans—people who choose to not consume any animal-sourced foods—are at risk because plant-sourced foods do not contain the vitamin in sufficient amounts to prevent vitamin deficiency.

Vegetarianspeople who consume animal byproducts such as dairy products and eggs, but not the flesh of any animal—are also at risk. Vitamin B12 deficiency has been observed in between 40% and 80% of the vegetarian population who do not also take a vitamin B12 supplement or consume vitamin-fortified food.

As with vegetarians, vegans can avoid this by consuming a dietary supplement or eating B12 fortified food such as cereal, plant-based milks, and nutritional yeast as a regular part of their diet. The elderly are at increased risk because they tend to produce less stomach acid as they age, a condition known as achlorhydria, thereby increasing their probability of B12 deficiency due to reduced absorption. Pain, which can vary in severity, is a common symptom of high mch.

Other common symptoms of high mch are Itching skin, Sleep disturbance, Tenderness in the soles of the feet, Itching, Tenderness in the palms and Bruising

Are lab test results always right?

While they do have to meet very high standards, they can be wrong sometimes. For example, you might get a false positive (the results say you have the condition you were tested for, but you really don’t) or a false negative (the results say you don’t have a condition, but you really do).

Lab test failures contribute to delayed or wrong diagnoses and unnecessary costs and care. For context, a 2014 study estimated that diagnostic errors happen about 12 million times per year in U.S. outpatients. This represents 1 in 20 adults. In case you think your blood test result doesn't make any sense, we recommend that you do the test again from HealthLabs as they perform testing using verified methods and they test blood only in the best CLIA certified labs. You won't need a doctor's referral or insurance.
