What causes headaches, nausea and sweating?

We often experience headaches in our daily lives because many diseases are interconnected. Headaches indicate that a part of the body has been diseased, and the pain enters the brain through nerve conduction. More severe headaches are accompanied by profuse sweating. For example, what is going on with headaches, nausea, and sweating? Let’s take a look at the explanation below.

1. Physiological night sweats: In childhood, the skin is very tender, contains more water, has abundant capillaries, has active metabolism, and the autonomic nervous system regulation function is not yet perfect, so it is easy to sweat during activities. Secondly, eating before going to bed can enhance gastrointestinal motility, increase gastric juice secretion, and increase sweat gland secretion, which can cause children to sweat more after falling asleep, especially within the first 2 hours of falling asleep. In addition, if the indoor temperature is too high, or the quilt is too thick, or electric blanket is used, it can cause profuse sweating during sleep.

2. Pathological night sweats: Some people sweat mainly in the first half of the night after falling asleep, which is often caused by low blood calcium. Low calcium can easily increase the excitability of the sympathetic nerves, just like turning on the "faucet" of the sweat glands. This situation is particularly common in children with rickets. However, night sweats are not a unique symptom of rickets. A comprehensive analysis should be conducted based on the child's feeding conditions, outdoor activities, etc. Blood calcium, blood phosphorus and wrist bone X-rays should also be checked to determine whether the child has active rickets.

3. Middle ear and inner ear diseases: Different ear problems can cause dizziness, such as otitis media, Meniere's disease, etc. Common cold viruses can also invade the inner ear and cause problems, and even lead to vomiting.

4. Drug influence: Some antihypertensive drugs, heart and diabetes drugs, and even cold sensitivity drugs may have this side effect.

5. Chronic diseases: If diabetes, bronchial disease, kidney disease, etc. are not well controlled, the above situation (such as low blood sugar) may also occur.

6. Arrhythmia: Heart disease causes abnormal oxygen supply to the brain and causes dizziness, among which slow heartbeat has a greater impact.

7. Anemia: During pregnancy or when women have heavy menstrual flow, the oxygen content in the blood will decrease, which will cause dizziness. Weak body and sweating.
