There are more clinical causes of drowsiness in guys, which are usually not more related to kidney deficiency. Narcolepsy may be due to poor sleep at night, or too short sleep, or sleep apnea, i.e. snoring while sleeping with intermittent breathing, which affects sleep quality and leads to biological clock disorders after a long time. In addition, if drowsiness is accompanied by fatigue, dizziness and mental confusion, it may be a sign of early neurasthenia. Inadequate nutrition and lower energy intake can also show signs of drowsiness. Obesity and overweight in adolescents can also cause drowsiness. Patients with hypothyroidism also often show signs of drowsiness due to low basal metabolic rate. Patients should pay attention to the regularity of work and rest, take outdoor exercise in appropriate amount, regulate their diet, increase protein intake, such as appropriate increase of fish, eggs, milk, soy products, pork liver, chicken and other foods, do not eat three meals a day too full, do less and more meals.
