What causes headache, nausea and vomiting?

We often encounter symptoms of physical discomfort in life. Most of the symptoms are fleeting and people do not feel them too deeply. However, headaches are a phenomenon that many people feel deeply. There are many reasons for headaches, and countless reasons can be found if you look into it. However, headaches, nausea and vomiting are relatively small in scope, and the scope of examination can be narrowed. Let's take a look at the explanation of what causes headaches, nausea and vomiting.

1. Food poisoning: The most common cause of headaches and discomfort is food poisoning. If we carelessly eat expired food or eat two incompatible foods, it will cause headaches and symptoms of vomiting and diarrhea. There are also some foods that can cause blood vessels to dilate and then affect the nerves. They can also affect the stomach, causing headaches and nausea, and causing headaches and boredom. These foods mainly include: chocolate, alcoholic beverages, raw dairy products, lemon juice, cheese, and red wine. We should eat and drink less to avoid causing headaches and discomfort and harming our bodies.

2. Sleep factor : Lack of sleep is one of the causes of headache and nausea. If you lack sleep for a long time, you may feel groggy when you wake up the next day, especially when you brush your teeth, you may feel nauseous and want to vomit. Of course, some people work overtime and stay up late for a long time, and they are prone to fatigue, which will cause headaches, so we must pay attention to the combination of work and rest in daily life.

3. Meningeal irritation : Sometimes people have headaches and the reason is probably because the meninges are irritated, which causes the blood vessels to shrink and increase the tension. Sometimes it may be a signal that the brain is short of oxygen and needs more oxygen. As long as more oxygen-containing blood flows into the painful area, the headache will disappear immediately.

4. Neuropsychiatric factors : Living in a social environment, we are always under the influence of society. If our bodies are subjected to some adverse effects, a series of excessive reactions will occur, such as bad mood, bad mood, excessive depression, irritability, etc., and this series of nervous and uneasy moods can easily lead to the occurrence of headaches and boredom symptoms. So we just need to always maintain a cheerful mood.
