Definition
Just like vomiting, nausea also reflects a very common (how unpleasant) symptom of numerous pathologies, or - more simply - expresses a disgust towards foods, smells or emotions brought to excess; we are talking about a condition of general malaise, arising in gastric level, which can trigger retching and vomiting.
Causes
Given that nausea is a symptom (not disease) of many pathological conditions, it is understandable that the underlying causes are many and varied: alcoholism, anxiety, appendicitis, bulimia, chemotherapy, depression, diabetes, drugs, gastroenteritis, pregnancy , HIV, flu, surgery, headache, intestinal obstruction, large and indigestible meal, birth control pill, tumors, dizziness, etc.
Symptoms
The main symptom accompanying nausea is certainly the perception of general malaise, often associated with drooling (salivary hypersecretion), retching and loss of appetite. As we have seen, in many cases, nausea is the stage that precedes vomiting.

Medicines
Since vomiting and nausea are closely related, it is clear that the two conditions are often analyzed together. Clearly, the severity of nausea must be analyzed and treated according to the cause that generated it.
NAUSEA GRAVIDICA: drugs
Anti-nausea medications should not be taken during pregnancy; rather, the woman can follow some simple rules to alleviate the symptoms:
- Eat little but often, preferring healthy and dry foods
- Prefer wholemeal bread and biscuits for breakfast
- Do not fast for too long: it is recommended to have more snacks throughout the day
- Avoid fried and heavy foods
- Drink ginger-based tea or herbal tea, a very useful natural remedy to combat nausea
- Practice relaxation techniques such as yoga and pilates
- Don't take too much liquid on an empty stomach
However, nausea and vomiting in pregnancy are generally mild and most often disappear after the third month of gestation; if not, the woman - after consulting her doctor - can take certain medications, such as:
- Promethazine (ex: Promet NAR, Farganesse, Fenazil). Dosage: 12.5 mg of active to be taken orally / intramuscularly / intravenously every 4-6 hours, as needed
- Metoclopramide (eg Plasil): drug belonging to the dopamine blocker class. Injecting, take 10 mg of the drug, three times a day, preferably before meals. Also available in tablets and syrup. It can be used in pregnancy to reduce nausea and possibly vomiting, although it is not the drug of choice for pregnant women.
- Prochlorperazine (eg Stemetil): belongs to the class of phenothiazines (cholinergic antagonists). Also this active ingredient, like the previous one, is not particularly used to treat pregnancy nausea, although in some cases it can be administered. Generally, it is recommended to take 5-10 mg of the drug (tablets), 3-4 times a day; alternatively, take 10-15 mg of active in capsule form every 12 hours. Rectally, the drug is taken at a dose of 25 mg, twice a day; intramuscularly, 5-10 mg as needed. Finally, the drug is also available as a solution for injection into a vein: 2.5-10 mg by slow IV injection. (no more than 5 mg per minute). Do not exceed 10 mg in a single dose. The drug is also indicated to quell vomiting after surgery.
Herbal medicine, phytotherapy and nausea in pregnancy
Nature also helps pregnant women overcome symptoms of nausea and vomiting; some plants, in fact, are particularly effective for remote purposes (consult your doctor):
chamomile (Chamomilla recutita)
cloves (Eugenia caryophyllata Thunb)
fennel (Foeniculum vulgare)
lemon balm (Melissa officinalis)
peppermint (Mentha piperita)
ginger (Zingiber officinal)
NAUSEA POST-SURGICAL INTERVENTION: drugs
We often talk about post-operative nausea: even in this circumstance, the causes can be different: anesthetic used, type of intervention, patient's health, age, sex, etc.
Typically, certain medications are prescribed to counteract nausea, such as:
- Metoclopramide and Prochlorperazine (previously analyzed)
- Cyclizine (eg. Marzine): the drug is an antihistamine indicated for the treatment of vomiting and nausea, especially in the case of surgery. It is recommended to take 50 mg of the drug, orally or intramuscularly, every 4-6 hours, depending on the need and the severity of the condition. Do not exceed 200 mg per day.
- Dexamethasone (eg. Decadron, Soldesam): this drug belongs to the class of corticosteroids and is generally used to treat nausea and vomiting after surgery, or following chemotherapy. Indicatively, the dosage is 8-10 mg of active ingredient every 12 hours, for 2 days; the therapy should be continued for another 2 days at a dosage of 4 mg every 12 hours. Consult your doctor: the dosage can be changed based on the severity of the condition.
In case of severe nausea and vomiting, it is also possible to take a couple of drugs with different therapeutic action.
IN GENERAL
Nausea and vomiting, conditions closely associated with each other, can cause dehydration and electrolyte imbalance: this complication is very dangerous, especially in children and the elderly. In this case, the patient undergoes rehydration therapy, which consists in the oral or intravenous administration of liquids enriched with glucose, potassium, sodium and rice starch.
