Dan Moore, certified physician assistant at McLaren-Greater Lansing Internal Medicine, a partner of McLaren-Greater Lansing, is treating the stomach flu.
Symptoms are: diarrhea, with or without nausea; vomiting; appetite loss; fatigue, and fever.
Those will usually clear up on their own, but if they last longer than about four days, or get worse, you should see a doctor.
It's important to drink fluids once your stomach is settled, to avoid dehydration.
Mr. Moore is also treating sinus infections this week.
Symptoms include: thick, yellow, foul-smelling nasal discharge; pressure or pain around the face and eyes; headache; congestion, and post-nasal drip.
Those symptoms can also be seen with a cold, but if sinus pain and thick yellow or green mucus last longer than a week, you should see a doctor. He or she may prescribe antibiotics.
You can use decongestants to help decrease swelling in the sinuses. Steam and hot showers will help with the mucus.
Your doctor may suggest nasal saline.
Drink lots of fluids and take Motrin or Tylenol for fever.
You should also see a doctor if your fever won't drop below 101 degrees with Tylenol or Motrin, if you have severe abdominal pain, or if you're losing weight.
Pay special attention to children and the elderly with those symptoms.
