The symptoms of hyperthyroidism are generally considered to be “irritability, excessive drinking and eating, weight loss, protruding eyes, sweating and palpitations”. However, the biggest problem is that the above symptoms often come quietly and without any special pain, and many patients cannot discover their condition actively. So how can ordinary people without professional medical knowledge easily identify hyperthyroidism? Most patients can self-assess at home by following these three steps. First, to determine if you have a new onset of the above mentioned hyperthyroidism symptoms, it is best to ask your close relatives or friends how they feel. Second, you can check if your neck is swollen or has a lump by looking at it first and then feeling it. How can I identify an enlarged thyroid or lump once I find an abnormality? The easiest way is to swallow, and if the enlarged tissue or lump moves with the swallow, then you can basically conclude that there is a problem with the thyroid gland. The third step is that most families now have automatic or manual electronic blood pressure meters. After measuring blood pressure and heart rate in a quiet state, use the following formula to calculate: (heart rate + high pressure value – low pressure value) – 111 to get the basal metabolic rate, and values exceeding -10~10 are considered abnormal. After the above steps of self-examination, if you find any problem, you should consult the endocrinology department or/and general surgery department of your local hospital in time, and you can get a clear diagnosis after medical examination and blood test of thyroid function by a specialist.
