Introduction
In general, persistent vomiting after surgery may be caused by incomplete metabolism of anesthetic drugs, surgical trauma and stimulation, fluid and electrolyte imbalance, decreased gastrointestinal function, or intestinal adhesions. If severe vomiting occurs after surgery, it is recommended to seek timely medical evaluation at a hospital and receive appropriate treatment under a doctor's guidance. It is also important to maintain healthy lifestyle habits in daily life.

Generally, persistent vomiting after surgery may be caused by incomplete metabolism of anesthetic drugs, surgical trauma stimulation, imbalance of water and electrolytes, decreased gastrointestinal function, or intestinal adhesion. Specific explanations are as follows:

1. Incomplete Metabolism of Anesthetic Drugs

Anesthetics are commonly used during surgery. If the anesthetic has not been fully metabolized after the procedure, symptoms such as vomiting and nausea may occur due to the drug's effects. This is usually a normal phenomenon and not a cause for concern; symptoms typically subside once the anesthetic wears off.

2. Surgical Trauma Stimulation

Trauma from surgery can impair gastrointestinal motility, leading to accumulation of gas in the stomach and causing symptoms such as acid reflux, nausea, and vomiting. Under medical guidance, patients may take medications such as ibuprofen sustained-release capsules or domperidone capsules for treatment.

3. Imbalance of Water and Electrolytes

After surgery, patients may develop imbalances in body fluids and electrolytes due to fasting before the operation, which can lead to nausea and vomiting. Appropriate supplementation of fluids and electrolytes can help alleviate these symptoms.

4. Decreased Gastrointestinal Function

If tracheal intubation is required during surgery, large amounts of gas may be introduced into the stomach, often resulting in nausea and vomiting. Patients should strictly follow medical advice and take medications such as domperidone capsules or compound digestive enzyme tablets for treatment.

5. Intestinal Adhesion

Following abdominal surgery, inadequate postoperative care may lead to intestinal adhesions, which can also cause vomiting. Under a doctor’s supervision, patients may use medications such as amoxicillin capsules or cefixime capsules for treatment.

If severe vomiting occurs after surgery, it is recommended to seek timely medical evaluation and receive appropriate treatment under a physician’s guidance. It is also important to maintain healthy lifestyle habits and avoid spicy or irritating foods to promote recovery.

How to recover from weakness and fatigue after surgery
Post-surgical weakness and fatigue can be recovered through nutritional supplementation, moderate physical activity, adequate sleep, emotional regulation, and prevention of complications. If abnormal conditions such as persistent high fever, difficulty breathing, or severe wound infection occur during recovery, prompt medical attention is required. After surgery, nutrition should be gradually restored, starting primarily with easily digestible liquid foods.

What should I do if there is still stabbing pain one month after surgery for a lung nodule?
One month after surgery for lung nodules, sharp pain may still persist. This can be managed through proper wound care, adjusting breathing techniques, reducing local inflammation, regulating psychological state, and planning activities appropriately. In most cases, symptoms can improve with scientific interventions. However, if the sharp pain lasts more than two weeks, worsens, or is accompanied by difficulty breathing or abnormal secretions, prompt medical attention is recommended.

What is the best medication to use after surgery for axillary odor?
There is no such thing as "the best medication to use after axillary osmidrosis surgery." Commonly used medications after axillary osmidrosis surgery include antibiotics, hemostatic agents, analgesics, wound-healing promoters, and topical disinfectants. These should be used according to postoperative recovery conditions and under medical guidance. Proper medication use can reduce the risk of infection and relieve discomfort. If symptoms such as wound redness, swelling, pus discharge, or persistent bleeding occur after surgery,

Will the armpits still sweat after surgery for palmar hyperhidrosis?
The surgery for palmar hyperhidrosis primarily targets excessive hand sweating by interrupting specific segments of the thoracic sympathetic nerves to reduce sweat gland secretion. However, since the axillary sweat glands are innervated by different nerves, the procedure does not directly affect their function; therefore, sweating in the underarms may remain unchanged after surgery. Some patients may develop compensatory hyperhidrosis postoperatively, characterized by increased sweating in areas such as the armpits and back following a reduction in palm sweating.

How long does it take to wake up from anesthesia after surgery?
The emergence time from general anesthesia is significantly influenced by the rate of drug metabolism. Short-acting anesthetic agents such as propofol may allow patients to regain consciousness within 30–60 minutes; however, long-acting drugs or combined anesthesia regimens may prolong recovery to 2–4 hours. Emergence may be further delayed in elderly patients, those with impaired liver or kidney function, or in cases involving prolonged surgical duration and higher doses of anesthetic agents.

What should be done about astigmatism after surgery?
Postoperative astigmatism can be managed through methods such as medical refraction diagnosis, wearing corrective glasses, adjusting visual habits, visual function training, and evaluation for secondary correction. Interventions should be scientifically determined based on the degree of astigmatism and ocular recovery status. If astigmatism is accompanied by eye pain, photophobia, or sudden vision loss, prompt medical attention is recommended. Accurate measurement of astigmatism degree should be conducted through professional refraction.
