Most of the time, night sweats are nothing to worry about, but they could indicate serious underlying issues especially when associated with other symptoms like weight loss, fever, pain, breathlessness, or diarrhoea. Below are some diseases that are often accompanied by night sweats.
Hyperthyroidism
An overactive function of the thyroid gland can cause night sweats. It is associated with other symptoms like excess hunger, weight loss, increased pulse rate, tiredness, diarrhoea, shaky hands, and feeling too hot.
Hypoglycemia
It means low levels of blood sugar. It occurs especially in diabetic patients if they stay hungry for a long period of time. It is therefore important that diabetics have snacks in between their meals.
