Doctors Near You for Nausea in Florianopolis

Nausea is an unpleasant, queasy sensation in the stomach that often precedes vomiting. It can be caused by a wide range of factors, including gastrointestinal disturbances, systemic illnesses, and neurological issues. The sensation of nausea is usually a symptom rather than a standalone condition and may be accompanied by symptoms such as dizziness, sweating, and increased salivation. The causes of nausea are diverse. Gastrointestinal issues such as infections (e.g., gastroenteritis), food poisoning, or chronic conditions like peptic ulcers and gastritis can lead to nausea. Gastroesophageal reflux disease (GERD) and irritable bowel syndrome (IBS) are also common culprits. Systemic illnesses, including viral infections, flu, or conditions like kidney failure or liver disease, can produce nausea as a secondary symptom. Neurological conditions such as migraines or increased intracranial pressure can cause nausea due to their effects on the brain. Other causes include motion sickness, which arises from conflicting signals between the inner ear and eyes, and pregnancy, particularly during the first trimester, leading to morning sickness. Medications, especially those that affect the gastrointestinal tract or have nausea as a side effect, can also induce this feeling. Psychological factors such as stress and anxiety can further contribute to nausea. Treatment for nausea focuses on addressing the underlying cause and alleviating symptoms. For nausea due to gastrointestinal issues, dietary modifications such as eating bland foods and staying hydrated can be beneficial. Over-the-counter antiemetic medications like meclizine or dimenhydrinate can provide relief for motion sickness or mild nausea. For pregnancy-related nausea, vitamin B6 supplements and ginger may be recommended. In cases where nausea is linked to medications, adjusting the dosage or switching to a different medication may help. If nausea persists or is severe, especially when accompanied by symptoms like persistent vomiting, abdominal pain, or dehydration, it is important to seek medical evaluation. Treatment may involve prescription medications, such as antiemetics or proton pump inhibitors, and further diagnostic testing to identify and address any serious underlying conditions.
