People with new gastrointestinal problems should consider if symptoms indicate a chronic or serious condition. If symptoms don't include bloody stools, fever, loss of bowel control, severe pain, or severe dehydration, doctors advise trying home remedies first.

The average cough, typically due to a cold or other respiratory virus, lasts three weeks or less. A lingering or chronic cough lasts eight weeks or longer. Most causes of chronic cough aren't serious, such as bronchitis, seasonal allergies, or medication side effects. People should see a doctor if over-the-counter treatments haven't worked or if they experience signs such as breathlessness, wheezing, chest pain, blood in the sputum, weight loss, or fatigue. Before an appointment, people should track their cough and note its patterns to offer clues for diagnosis.
