What to do if you feel nauseous and want to vomit after taking medicine

Some drugs are very irritating, and patients will feel nauseous after taking the medicine. At this time, patients must control themselves, or sit quietly to alleviate this situation with their own will, otherwise they may vomit and cause the stomach to relax, thus developing stomach problems. In addition, they may feel dizzy after taking the medicine. So what should patients do if they feel nauseous and want to vomit after taking the medicine?

Dizziness, also known as vertigo, is a subjective sensory abnormality. It can be divided into two categories: one is rotational vertigo, which is mostly caused by dysfunction of the vestibular nervous system and cerebellum.

The main feeling is a tilting sensation, with one feeling oneself swaying or the scenery spinning. The second is general dizziness, which is mostly caused by certain systemic diseases, and is mainly characterized by a feeling of dizziness and a feeling of heaviness in the head and lightness in the feet.

Classification and common diseases

Dizziness is a common symptom rather than a separate disease. Therefore, we can classify and describe the diseases that cause dizziness so that everyone can have a deeper understanding of "dizziness".

1. Rotational vertigo can be divided into two categories according to its cause: peripheral vertigo and central vertigo.

(1) Peripheral vertigo: refers to vertigo caused by lesions in the inner ear labyrinth or vestibular nerve. It is common in Meniere's disease (formerly Meniere's disease), labyrinthitis, drug-induced vertigo (caused by the use of drugs such as streptomycin or gentamicin) and vestibular neuritis.

(2) Central vertigo: refers to vertigo caused by lesions of the brainstem, cerebellum, cerebrum and spinal cord. It is common in vertebral-basilar artery insufficiency, intracranial tumors, intracranial infection, multiple sclerosis, vertigo epilepsy and traumatic vertigo.

2. General vertigo

(1) Cardiac vertigo: common in arrhythmias, heart failure, etc.

(2) Pulmonary vertigo: can be seen in lung dysfunction caused by various reasons.

(3) Ocular vertigo: common in refractive errors, retinal arteriosclerosis, hemorrhage and ophthalmoplegia.

(4) Hypertensive vertigo: Both high blood pressure and low blood pressure can cause vertigo.

(5) Others: Anemia, cervical spondylosis, acute fever, gastroenteritis, endocrine disorders and neurosis can all cause dizziness.

1. If an elderly person with anemia experiences dizziness, fatigue, or pale complexion, he or she should go to the hospital for a check-up to see if he or she has anemia. If the elderly do not pay attention to nutritional health, they are likely to suffer from anemia. In addition, elderly patients with indigestion, peptic ulcer, gastrointestinal bleeding and chronic inflammatory diseases may all develop secondary anemia.

2. High blood viscosity Hyperlipidemia, thrombocythemia, etc. can cause high blood viscosity and slow blood flow, resulting in insufficient blood supply to the brain and symptoms such as fatigue, dizziness, and weakness. There are many reasons for high blood lipids, the most important of which is unreasonable diet structure.

3. Patients with cerebral arteriosclerosis feel dizzy and often suffer from insomnia, tinnitus, emotional instability, forgetfulness, and numbness in the limbs. Cerebral arteriosclerosis reduces the inner diameter of blood vessels, reduces blood flow in the brain, causes insufficient blood and oxygen supply to the brain, and causes dizziness.

4. Cervical spondylosis often causes tightness in the neck, limited flexibility, occasional pain, numbness and coldness in the fingers, and a feeling of heaviness. Cervical spondylosis compresses the cervical vertebral arteries, causing insufficient blood supply to the brain, which is the main cause of dizziness caused by this disease.

5. Hypertension In addition to dizziness, patients with hypertension often also experience discomfort such as headache, palpitations, irritability, tinnitus, and insomnia.

6. Heart disease In the early stages of coronary heart disease, some people may experience headaches, dizziness, weakness in the limbs, and difficulty concentrating. Dizziness is mainly caused by atherosclerosis of the coronary arteries of the heart, resulting in insufficient blood supply.
