Listening and Smelling for Signs

This means paying attention to how the person talks and the sounds they make when they breathe or cough. You also smell their breath and body. Some health issues can make bad smells. This could be from sores, growths, or boils. Certain quick-spreading sicknesses, or problems with the liver and kidneys, can also have special smells. Plus, if someone has too much heat in their lungs and belly, they might have bad breath. This can also happen if they have trouble digesting food.
