Data provided by the American Patient Safety Foundation shows that even the best doctors are bound to make mistakes, and about 40% of medical errors are misdiagnoses. The American "Red Book" magazine recently published an article pointing out that women are most likely to be misdiagnosed with four diseases.

1． Heart disease

Symptoms: Fatigue or difficulty breathing, chest tightness and chest pain, and/or heart palpitations.

Often misdiagnosed as: excessive stress or panic disorder. Reason for misdiagnosis: Heart attack symptoms in women are slightly different from those in men. Fatigue or shortness of breath may be early symptoms. Studies have found that more than half of heart disease, the number one killer of American women, is misdiagnosed at the time of onset.

Expert advice: If you have the above symptoms, you should see a cardiologist first.

2． Symptoms of stroke

Symptoms of stroke: numbness on one side of the body, headache, dizziness, sudden blurred vision, loss of balance or muscle coordination, sometimes accompanied by slurred speech, etc.

Often misdiagnosed as: vertigo,

Migraine or inner ear disease. Reasons for misdiagnosis: 14% of stroke cases under the age of 45 are misdiagnosed. Patients are young and healthy, and emergency doctors often first assume that their condition is not serious. Once misdiagnosed and the best time for treatment is missed, it will lead to permanent speech and visual damage and paralysis.

Expert advice: If you have numbness on one side of your body or are accompanied by the above-mentioned stroke symptoms, especially if the symptoms last for more than 1 hour, you should seek medical treatment immediately and remind the doctor that it may be a stroke.

3. Hypothyroidism

Symptoms: Depression, fatigue, weight gain, insomnia, muscle pain or stiffness, etc.

Often misdiagnosed as: depression

. Reasons for misdiagnosis: Persistent low mood is often diagnosed as depression by doctors without thinking of hypothyroidism.

Experts recommend: If your mood does not improve after taking medication, you should ask for a thyroid-stimulating hormone (TSH) blood test.

4.

Temporomandibular joint disorder syndrome symptoms: headache, tinnitus or earache, accompanied by back, neck and tooth pain.

Often misdiagnosed as: migraine or ear disease. Reasons for misdiagnosis: Inflammation of the temporomandibular joint, radiating pain that can lead to headaches or earaches. Temporomandibular joint disorder syndrome is best managed by a dentist and can be easily relieved.
