It's like a little stroke. Your father is middle-aged. This situation cannot be ignored. I suggest you go to the hospital to investigate. It may also be caused by overwork.

Pay attention to develop good living habits and scientific eating habits. Pay attention to eat less and eat more, chew slowly, eat three or four meals, eat seven or eight full meals, don't overeat, eat low sugar, salt and fat, quit smoking and drink less, and give up irritating foods such as peppers. Of course, you can't eat irritating food. Usually eat more fresh green vegetables and fruits, as well as carrots, black fungus, oatmeal, oatmeal, jujube, tomatoes and so on. When stewing soup, please pay attention to remove the oil layer above before drinking, drink more boiled water, and drink a cup of boiled water about half an hour after waking up before going to bed. You can't get up immediately after waking up in the morning, stay for 4 or 5 minutes, and then get up. You should keep a cheerful mood and a stable mood, chat with everyone more, talk and laugh, and don't be too emotional, don't sulk often, take more walks after meals, exercise moderately, and take sweating as the biggest activity.

I wish your father a speedy recovery and a happy and healthy family!
