Will dieting cause symptoms of vomiting

Dieting may cause nausea and vomiting symptoms, mainly related to factors such as hypoglycemic reactions, imbalanced gastric acid secretion, electrolyte imbalances, increased psychological stress, and decreased basal metabolic rate.

1. Hypoglycemic reaction:

Long term fasting or extremely low calorie intake can cause a sudden drop in blood sugar levels, triggering sympathetic nervous system excitation. The body is responsible for maintaining energy supply to important organs, which may cause hypoglycemic reactions such as dizziness, cold sweat, nausea, and in severe cases, jet vomiting. It is recommended to adopt a small amount of multiple meals and replenish an appropriate amount of compound carbohydrates every 3-4 hours.

2. Imbalance of gastric acid secretion:

The stomach continuously secretes gastric acid on an empty stomach, and a lack of food neutralization can cause gastric acid to irritate the gastric mucosa. Long term dieting may induce bile reflux, and when the sphincter muscle at the gastroesophageal junction relaxes, sour and bitter fluids reflux into the esophagus, causing a burning sensation and dry vomiting. You can try drinking a small amount of soda water in portions to alleviate the symptoms.

3. Electrolyte imbalance:

Strictly controlling diet can lead to mineral deficiencies such as sodium, potassium, and magnesium. When the blood sodium concentration is below 135mmol/L, the imbalance of intracellular and extracellular osmotic pressure may cause brain cell edema and stimulate the vomiting center in the medulla oblongata. Excessive sweating after exercise can exacerbate electrolyte loss, so it is important to supplement drinking water that contains electrolytes.

4. Increased psychological stress:

Excessive attention to weight numbers may activate the hypothalamic pituitary adrenal axis, and elevated cortisol levels may delay gastric emptying. Some people may experience eating anxiety when they are hungry, and this tense emotion is transmitted to the digestive tract through the vagus nerve, manifested as stomach spasms and nausea.

5. Decreased basal metabolic rate:

Long term insufficient calorie intake can activate protective mechanisms in the body, leading to a 30% decrease in thyroid hormone T3 levels. Reduced metabolic rate leads to decreased digestive function, and when gastric motility is insufficient, food retention can easily produce a putrid odor, triggering the vomiting reflex. This situation requires a gradual recovery of dietary calories.

Scientific weight loss should ensure a daily intake of no less than 80% of the calories required for basal metabolism, and adult women are recommended to consume no less than 1200 calories. Priority can be given to choosing high protein and high fiber foods to prolong satiety, such as eggs, oats, broccoli, etc. Combining resistance training can maintain muscle mass, and brisk walking for 30 minutes three times a week can effectively prevent side effects of dieting. If there is persistent vomiting or vomiting blood, seek medical attention immediately to investigate organic diseases such as peptic ulcers.
