Development mechanisms
To understand why sudden, causeless nausea occurs, it is necessary to understand the mechanisms of its development. Doctors distinguish several varieties:
- central;
- reflex;
- visceral;
- motor;
- hematogenous-toxic.
Central
The cause of the development of the central variety can be inflammatory and infectious pathologies occurring directly in the brain and/or its membranes. Provocateurs include: concussions, head injuries, benign/malignant brain tumors. Accompanies arterial hypertension and may indicate the development of a hypertensive crisis.
Visceral
Visceral nausea is a sign of problems with the gastrointestinal tract (GIT). It occurs as a symptom of stomach cancer, ulcerative pathologies, inflammation of the pancreas, cholecystitis, gastritis.
Nausea may be a sign of gastrointestinal disease
This type often develops against the background of the following pathologies:
- inflammation of the pharynx;
- pleurisy;
- myocardial infarction;
- renal colic;
- thrombosis.
Motor
Motor nausea develops during inflammatory/infectious pathologies of the ear, as well as disturbances in the functioning of the vestibular apparatus.
Hematogenous-toxic
Sudden nausea in this case occurs as the body’s response to exposure to toxic substances. Often found in patients diagnosed with renal failure, endocrine pathologies, all types of tumors, as well as during pregnancy.
Important! The cause of its development may be the use of certain medications. In this case, it is considered as a side effect.
Nausea before bed: explanation of the phenomenon
Nausea occurs for many reasons. The main one is irritation of the splanchnic and vagus nerves. At the same time, the tone of the stomach walls decreases and peristalsis slows down.
The visual and olfactory sensors are irritated. The vomiting center is excited, first begins to feel nauseous, then vomiting begins.
Nausea occurs more often in women than in men due to their greater sensitivity and nervous excitability. But the reasons for its occurrence are almost the same, except for one thing: the stronger half does not suffer from ailments that appear as a result of pregnancy. This symptom comes in different types:
- toxic, resulting from poisoning with poisons, toxins;
- cerebral, caused by brain diseases, hypertension;
- metabolic, based on metabolic and endocrine processes disorders;
- reflex, which occurs when the gastrointestinal tract is irritated;
- vestibular, associated with impaired coordination of movement, accompanied by dizziness.
For successful therapy, it is necessary to conduct diagnostic studies and collect a detailed medical history. Then it will be easier to deal with the cause of the problem, unpleasant symptoms can be relieved faster, and the patient’s condition can be improved.

Causes not related to existing diseases
Severe nausea sometimes occurs as the body’s response to uncomfortable conditions. Quite often, attacks occur against the background of a weak vestibular apparatus. If a person gets motion sickness while traveling, then taking special pills will help get rid of the nausea.
The causes of sudden nausea and subsequent vomiting in an adult may lie in psychological problems. Provoking factors can be a state of severe fear, being in a stressful situation, or severe nervous tension. Breathing exercises will help relieve an attack.
Mild lightheadedness with vomiting sometimes develops in a person after arriving in a new, unfamiliar place
There are other reasons. This:
- Severe physical or emotional fatigue, lack of sleep. The body needs daily rest and if it does not receive it, it responds with various uncomfortable conditions. One of these is attacks of severe nausea.
- Poisoning, development of intestinal infection. Emptying of the stomach is typical for the pathology, but sometimes the patient feels only nausea, without vomiting.
- Side effect caused by taking medications. Some drugs can cause nausea and even vomiting.
- Development of gestation. The first months of bearing a child are characterized by constant attacks of lightheadedness. Sometimes they end in vomiting.
- Migraine. For this type of headache, nausea is a typical condition.
- Brain concussion. The pathology is accompanied by dizziness and severe nausea. Sometimes the latter ends in vomiting.
The cause of lightheadedness can be a person’s diet. It is provoked by hunger, overeating, and excessive indulgence in sweets.
Reasons of a physiological nature
It is unfortunate that nausea that lasts for a long time almost never brings the desired relief. Here it can be compared to a sudden attack that ends in vomiting. On the contrary, nausea in the evening is debilitating, prevents normal sleep and significantly reduces the quality of sleep. This is especially unpleasant if other symptoms are added to this process, for example, weakness, stomach pain or dizziness, or even all at once.
Most often, the feeling of being sick is not accompanied by illness. Nausea can be caused by poor diet or lifestyle, that is, external factors that can be easily detected and corrected. Polluted and gassed city air can provoke attacks in the evening, since all the dirt that rises into the air during the day falls down, having a negative impact on people with poor health. And if you have irritating substances in your bedroom such as perfumes, tobacco smoke, household chemicals, etc., then nausea in the evening simply cannot be avoided.
The most common cause of nausea in the evenings is living under severe stress and overwork. These factors provoke an increase in pressure, which, in turn, leads to nausea, weakness, loss of orientation, cold sweat, dizziness, sparks and darkness in the eyes. Hypertensive people are more likely than others to feel evening nausea, so if you have a tendency to increase blood pressure, it is better to have a blood pressure monitor and medications in the house to bring you to your senses.
Nausea at night can be triggered by noticeable overeating the day before, especially if you allowed yourself to consume a large amount of fried and fatty foods. The digestive system simply turns out to be unprepared to go into emergency mode at a time when it is supposed to rest, so your body simply strives to get rid of the excess, provoking vomiting. This is a normal protective reaction of the body to overeating.
Often people experience nausea after heavy alcoholic libations, which is natural, since alcoholic drinks are a real poison for your body. The liver neutralizes a small amount of alcohol using its own enzymes, but such work is very difficult for it.
If you’ve obviously had too much alcoholic drinks, then the body again turns on a defensive reaction: you feel sick at night if you’ve consumed too much alcohol in the evening.
Nausea caused by physiological reasons occurs quite rarely and is neutralized as soon as you eliminate the immediate cause of your cloudiness. It is the ability to eliminate nausea at night by stopping the causes of its manifestation that allows us to say that there are no pathologies in your body.
Attacks of nausea due to illness
Nausea occurs as a symptom of an existing pathology. Seizures can be provoked by:

- Inflammation of the appendix. Nausea is one of the possible signs of a pathological condition. Additional signs include pain in the lower abdomen (left quadrant) and increased body temperature.
- Hypertonic disease. The development of an attack of lightheadedness is accompanied by an increase in blood pressure and redness of the face.
- Heart failure. The disease is characterized by prolonged nausea.
- Hypothyroidism. Nausea is also one of the signs of pathology of the endocrine system. As a rule, it is accompanied by weakness and lack of appetite.

If pathological symptoms develop, in order to diagnose the pathology, consultation with a qualified specialist is necessary.
What to do - how to quickly relieve signs of nausea?
It is believed that treatment of nausea is not advisable, since it is not an independent disease. This is just one of the symptoms of the underlying disease. Despite this, there is one proven and universal way to relieve such an unpleasant sign of the disease. It is necessary to take a horizontal position. Namely, lie on your stomach. The right hand is clenched into a fist and placed under the peritoneum directly into the navel area.
You need to lie on the formed fist for 5-10 minutes and take sharp, deep breaths. In most cases, during the specified time, a reflex relaxation of the muscle fibers responsible for spasm and vomiting occurs. This method is indicated for everyone except pregnant women and children under 6 years of age.
When there are any health disorders, the human body begins to signal about it. One of the warning signs is causeless nausea. Everyone is accustomed to associating this symptom in women with pregnancy, but this is not always the case. Nausea can be bothersome in the morning or throughout the day, be long-lasting or short-term, end with vomiting or go away on its own and unexpectedly. This unpleasant sensation significantly reduces a woman’s quality of life. In case of such deterioration in health, it is advisable to immediately consult a doctor and undergo an examination.
Causes of morning sickness
There are many reasons for nausea that occurs in the morning. The most common are the following: evening overeating, morning hunger, excessive intake of alcoholic beverages, taking medications on an empty stomach.
Sudden nausea in the morning may be the first sign of pregnancy
One of the harmless reasons why there are attacks of lightheadedness in the morning is pregnancy. Many women suffer from this symptom of early toxicosis. As a rule, the condition stabilizes by the beginning of the second trimester.
Attacks in the evening and at night
Most often, uncomfortable conditions for a person develop in the evening and at night, nausea is no exception. Severe evening nausea can be a sign of significant physical fatigue. The reason could be, for example, irregular working hours.
The next likely reason is overeating in the afternoon. As evening approaches, the rate of metabolic reactions decreases, which leads to slower functioning of the digestive tract. Food stays in the stomach for a long time, which causes nausea.
To avoid the development of an uncomfortable condition, it is necessary to refrain from eating foods that are difficult to digest. The food should be light and the portions should be small. Pathological conditions, in particular dysbacteriosis or inflammation of the appendix, can also be causes of evening and night nausea.
Late intake of medications can provoke an attack of lightheadedness in the evening or at night
Methods of therapy and relief from symptoms
You can get rid of attacks that torment you at night and prevent you from getting a good night’s sleep using various methods. These include medications, folk recipes and nutritional correction.

Nausea is a very unpleasant condition that requires urgent action. If it becomes permanent and is accompanied by the development of additional pathological symptoms, it is recommended to obtain qualified medical advice and undergo a full medical examination.
Methods for treating the syndrome
The manifestation of nausea in the evening, especially if this ailment has become regular and is accompanied by other alarming symptoms, is a reason to consult a doctor. It will be necessary to undergo various examinations to make a diagnosis and prescribe treatment.
Attention! When nausea is accompanied by abdominal pain, you should call an ambulance. These may be signs of a serious pathology, perhaps even life-threatening to the patient.
Medication
There are medications to relieve nausea. Their action is aimed at increasing the secretion of bile. These are “Allohol”, “Holenzym”, “Silimar”, they are prepared from natural ingredients. Medicines help remove toxins from the body, relieve intoxication and thereby alleviate the condition. You can use Holosas syrup, made from rose hips.
The drug Cerucal has a different mechanism of action. It is based on the blocking of seratonin and dopamine receptors by the substance metoclopromide. The threshold of excitability of the vomiting center increases, the motor activity of the walls of the esophagus decreases, and the movement of food through the small intestine accelerates.
If the cause of nausea is endocrine problems, diseases of the nervous system and other pathologies, only a doctor should select medications.
Advice! When the cause has not yet been established, a woman should not use medications or even herbs without the permission of a specialist. In the case of early pregnancy, they can cause irreparable harm to the unborn child.
