A distinction is made between vomiting in different cases, including:

Dangerous conditions such as intestinal obstruction, pleurisy, or perforation of an organ in the digestive system.

Include the following:

Anticholinergic drugs: They are used for treatment in a limited way because of the many side effects that they cause and because of their low efficacy. It is only used for movement related diseases.
Drugs that block histamine receptors: effective in treating migraines, in particular, and in movement diseases that result from an action on the balance center in the inner ear. It has a central anti-emetic effect.
Phenothiazines: substances with anti-emetic properties. It acts on different receptors in the brain. It is effective in treating migraine, basically.
Butyrophenones: Known as a treatment for mental illness. There are few attempts to use it in the treatment of migraine.

Cannabinoids: marijuana mimics. Reports regarding the effect of these substances are few and not proven.
Corticosteroids: They are used only in emergency situations to treat brain edema.
Benzodiazepines: They help treat sleep disorders and anxiety. These drugs work by inhibiting the reticular activating system responsible for nervous alertness.

movement stimuli
Motion stimulators are primarily effective in the treatment of gastroesophageal reflux disease and gastroesophageal reflux disease, and include:

Serotonin 4 agonists: This family of drugs stimulates muscle action throughout the digestive tract. Muscle action generally affects the release of the neurotransmitter acetylcholine from the nerve terminals.
Macrolide antibiotics: Stimulate gastric emptying by secreting motilin from the duodenum.

7. White blood cell count
Infectious mononucleosis, or the kissing disease or mono, is transmitted between people through saliva and leads to stomach pain and chills.
8. Pneumonia
Pneumonia is an infection of the lung that causes inflammation of the alveoli.
