Keshan Disease: Signs, Causes, And How To Treat
Keshan disease is a serious heart condition that can affect individuals of all ages. This illness is caused by a deficiency in a crucial mineral that the body needs to function properly. Understanding the underlying causes of Keshan disease is essential for prevention and management. By addressing the root cause of this condition, individuals can take proactive steps to maintain heart health and overall well-being.
What Are the Symptoms of Keshan Disease?
Keshan disease symptoms include fatigue, chest pain, irregular heartbeat, and shortness of breath. Patients may experience weakness, poor appetite, and weight loss. Swollen joints, pale skin, and difficulty concentrating are common. Seek medical attention if you have these symptoms, especially if you live in regions with selenium-deficient soil. Treatment involves selenium supplementation and managing heart complications.
- Fatigue: People with Keshan disease may experience persistent tiredness and lack of energy, even after getting enough rest.
- Chest pain: Individuals with Keshan disease may feel discomfort or tightness in their chest, which can worsen with physical activity or stress.
- Shortness of breath: Breathing difficulties, especially during exertion or when lying down, can be a common symptom of Keshan disease.
- Irregular heartbeat: Keshan disease can cause abnormalities in heart rhythm, leading to palpitations or a sensation of fluttering in the chest.
- Muscle weakness: Weakness in the muscles, particularly in the arms and legs, may be a symptom of Keshan disease, affecting daily activities and mobility.

Get A Second OpinionCauses of Keshan Disease
This deficiency is often linked to poor dietary intake or living in regions with selenium-deficient soil. Additionally, viral infections may play a role in triggering the disease. Selenium is crucial for maintaining heart health, and its deficiency can lead to the development of Keshan disease.
- Selenium deficiency in the diet is a major cause of Keshan disease, as this essential mineral plays a critical role in protecting against viral infections.
- Chronic exposure to environmental toxins such as mercury, cadmium, and lead can contribute to the development of Keshan disease by impairing the function of the heart muscle.
- Inadequate intake of essential nutrients like vitamin E, which acts as an antioxidant in the body, can increase the risk of developing Keshan disease due to heightened susceptibility to oxidative stress.
- Viral infections, particularly coxsackievirus, have been linked to the onset of Keshan disease, as they can trigger an inflammatory response that damages the heart tissue.
- Genetic factors may also influence the risk of Keshan disease, as certain genetic predispositions can affect how individuals metabolize selenium and respond to oxidative stress.
Types Of Keshan Disease
Keshan disease comes in two main types: endemic and sporadic. Endemic Keshan disease is linked to specific geographic regions with low selenium levels in the soil, while sporadic Keshan disease occurs in areas with adequate selenium but is influenced by other factors like diet and genetics. Both types can lead to serious heart complications if left untreated.
- Classic Keshan disease is a severe form of selenium deficiency that primarily affects children and pregnant women in regions with low soil selenium levels, leading to cardiomyopathy and heart failure.
- Subclinical Keshan disease refers to a milder form of selenium deficiency that may not present with obvious symptoms but can still have detrimental effects on overall health, such as decreased immune function and increased susceptibility to infections.
- Acute Keshan disease is a rare and severe manifestation of selenium deficiency characterized by rapid-onset congestive heart failure, arrhythmias, and cardiogenic shock, requiring immediate medical intervention.
- Chronic Keshan disease develops over a prolonged period due to inadequate selenium intake, resulting in progressive heart muscle damage,
Risk Factors
Keshan disease is linked to various risk factors that increase susceptibility to the condition. These include selenium deficiency, living in regions with low soil selenium levels, consuming foods with low selenium content, and exposure to certain environmental toxins. Additionally, individuals with weakened immune systems or poor overall health are also at a higher risk for developing Keshan disease.
- Low selenium intake in the diet is a significant risk factor for Keshan disease, as selenium deficiency can impair the function of enzymes involved in protecting against oxidative stress.
- Living in regions with selenium-deficient soil increases the likelihood of developing Keshan disease, since the mineral is crucial for the production of selenoproteins that support heart health.
- Certain genetic factors may predispose individuals to Keshan disease, as variations in genes involved in selenium metabolism can impact the body's ability to utilize this essential mineral effectively.
- Inadequate intake of other nutrients like vitamin E and vitamin D, which work synergistically with selenium to maintain heart function, can also contribute to the risk of developing Keshan disease and may exacerbate the effects of selenium deficiency.

Book an AppointmentDiagnosis of Keshan Disease
Keshan disease is diagnosed through a combination of medical history, physical examination, and blood tests to check for abnormalities in the heart and overall health. Your healthcare provider may also recommend imaging tests like echocardiograms or MRIs to assess heart function. Prompt diagnosis is crucial for timely treatment and management of Keshan disease.
- Blood tests can help diagnose Keshan disease by measuring levels of selenium, glutathione peroxidase, and other relevant markers.
- Electrocardiogram (ECG) can detect abnormalities in heart function, such as arrhythmias or conduction disturbances, which may be present in individuals with Keshan disease.
- Echocardiography is a non-invasive imaging technique that can assess the structure and function of the heart, aiding in the diagnosis of Keshan disease-related cardiac abnormalities.
- Chest X-rays can reveal cardiomegaly (enlarged heart) or other signs of heart failure that may be indicative of Keshan disease.
- Tissue biopsy, particularly of heart tissue, can provide definitive evidence of Keshan disease by identifying characteristic pathological changes associated with the condition.
Treatment for Keshan Disease
Treatment for Keshan disease typically involves selenium supplementation to correct the deficiency and prevent further complications. Your healthcare provider may recommend a specific dosage based on your individual needs. It is important to follow their guidance closely and regularly monitor selenium levels through blood tests. In some cases, additional treatments such as heart medications or surgery may be necessary to manage any heart-related complications.
- Selenium supplementation is a key treatment for Keshan disease, as selenium deficiency is a major factor in the development of the condition, and restoring selenium levels can help improve heart function and overall health.
- Cardioprotective medications such as beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, and diuretics may be prescribed to manage symptoms and prevent complications in patients with Keshan disease.
- Regular cardiac monitoring and follow-up appointments with a healthcare provider are essential for individuals with Keshan disease to ensure proper management of their condition and adjustments to treatment as needed.
- Dietary modifications, such as increasing intake of selenium-rich foods like nuts, seeds, fish, and whole grains, can complement selenium supplementation and help improve overall nutritional status.
