I am 22 yrs old men.My height is 157cm and weight is 70kg.My hand shears when I have hunger.I don't smoke.I can't concentrate on my work due to hunger.Is it due to overweight?But when my weight was 55 kg,at that time my hands were also sheared due to hunger.But I talked with my overweight people and people who smokes.They don't have such problem.Also when I lift weight or do physical activity,after that my hands shears.Also when I heard a big noise or when I quarrel with someone or argue with someone my hands started shearing and there is change is my voice and my heart bits started increasing.Is it a
thyroid problem? My mother has also a problem of thyroid.
