there are three chambers to the lungs and to listen to all of them efficiently-the dr has to put the stethoscope in 4 different places. once on your upper back (near your shoulder blades), once on the sides of your waist, once on your lower back and then in the front at the center of your chest which is close to your heart.
You might be wondering what causes stomach bloating. There are dozens of different sneaky reasons you might develop a bloated stomach â allergies, hormonal imbalances, thyroid dysfunction, gut troubles and more.
Bloating is most often caused by trapped gas in the small intestine. This can cause flatulence (passing of excessive gas/wind) painful stomach ache and an uncomfortable feeling when wearing tight clothes. Bloating can also occur as a result of food intolerance, insufficient digestive enzymes in your stomach or lack of good intestinal flora (good bacteria normally present in the gut).
