Introduction
Palpitations, dizziness, and nausea may be caused by gastrointestinal coldness, cardiac neurosis, cerebral arterial insufficiency, arrhythmia, hypertension, renal insufficiency, hepatic dysfunction, or unstable blood glucose control. It is recommended that the patient undergo further examinations, including transcranial Doppler, ambulatory electrocardiography (Holter monitoring), liver function tests, renal function tests, blood glucose measurement, and complete blood count. Anti-inflammatory treatment with cephalosporins is also recommended.

　　In daily life, everyone inevitably experiences physical discomforts such as dizziness, palpitations, and nausea—symptoms that are relatively common. However, if these symptoms occur frequently, they can significantly impair quality of life, and their recurrence may indicate underlying medical conditions. Only after identifying the precise cause can targeted treatment be initiated. So, what causes palpitations, dizziness, and nausea?

　　What Causes Palpitations, Dizziness, and Nausea?

　　Palpitations, dizziness, and nausea may stem from various causes, including gastrointestinal cold (a traditional Chinese medicine concept referring to functional gastrointestinal disturbances), cardiac neurosis, cerebral arterial insufficiency, arrhythmias, hypertension, renal insufficiency, hepatic dysfunction, or unstable blood glucose control. Patients are advised to undergo further diagnostic testing, including transcranial Doppler ultrasound, ambulatory electrocardiography (Holter monitoring), liver function tests, renal function tests, blood glucose measurement, and complete blood count (CBC). If symptoms result from gastroenteritis (“gastrointestinal cold”), appropriate anti-inflammatory therapy—such as cephalosporins or quinolone antibiotics—may be indicated.

　　If hypertension is the underlying cause, active blood pressure control is essential. Additionally, certain medications may be used in combination to improve cerebral arterial perfusion. Patients should visit a hospital for investigations such as electrocardiography (ECG), CBC, and brain MRI to determine the etiology and initiate prompt, appropriate treatment. For hypertension-related symptoms, nifedipine sustained-release tablets may be prescribed; combining this medication with lifestyle modifications can help alleviate symptoms. In cases of anemia, supplementation with iron, folic acid, and vitamin B12 is recommended.

　　Patients are advised to ensure adequate rest and maintain a calm, relaxed mental state, both of which support symptom improvement. We hope this information proves helpful to you.

What are the symptoms of moderate anemia?
Typical symptoms of moderate anemia include pallor of the skin and mucous membranes, general weakness and easy fatigue, shortness of breath and palpitations, dizziness, headache, difficulty concentrating, decreased appetite, and indigestion. If one or more of these symptoms occur, it is recommended to promptly visit a正规 hospital for a complete blood count (CBC) test to confirm the diagnosis. Insufficient hemoglobin leads to reduced oxygen-carrying capacity of the blood, resulting in pallor of the face, lips, and nail beds.

What are the symptoms of mild anemia?
Common symptoms of mild anemia include pale complexion, dizziness, fatigue, palpitations, shortness of breath, difficulty concentrating, and loss of appetite. If one or more of these symptoms occur, it is recommended to seek medical attention promptly for a complete blood count (CBC) test to confirm the diagnosis. In anemia, the oxygen-carrying capacity of red blood cells in the blood decreases, leading to insufficient oxygen and blood supply to tissues such as the facial skin, lips, and nail beds, resulting in a pale, bloodless appearance.
