Question

UNIT-3 “DIGESTION”

Case Study
Richa, a 24-year-old lady, was recently married and started doing lots of homecooking. At her annual gynaecological exam, she asks her women’s healthphysician if she can refer her to a physician specializing in “stomach or heartproblems.” Apparently, Richa has been feeling a pain in her chest or upperabdomen nearly every evening, especially right before bed or right when she liesdown. Her husband tells her it must be heartburn, but truthfully Richa did notunderstand what heartburn really meant until she googled it. Now she is startingto suspect that maybe her diet is involved.

Read the following excerpt from the patient’s interview:-
Doctor: So tell me more about this pain you mentioned.
Richa: Well the pain in my chest is happening most nights around 9 or 10pm. Weusually eat dinnerlate--around 8pm because it takes a while to cook after we get home from work.

Doctor: Does anyone you know have this problem?
Richa: My mom always used to complain about “the burn in her chest” after ourspicier meals, but I thought she was being dramatic. Now I think I know what she meant.

Doctor: Do you have any history of other medical conditions in your family?
Richa: My dad died of a heart attack when I was 14. My grandparents all passedfrom different types of cancer. My mom is pretty healthy.

Doctor: What have you eaten so far today? (It is 11am)
Richa: A chorizo & pepper omelet that my husband made for me. 

Doctor: Ok, let’s get back to the chest pain. When didyou first started noticing thisproblem?
Richa: About six weeks ago

Doctor: And how often does it happen?
Richa: Every night. The only time I don’t get it is at night if I eat something reallybland for dinner, like a sandwich.

Doctor: Do you have any other symptoms or issues besides the chest pain?
Richa: Well, I’ve noticed more of a dry cough lately and my throat keeps gettingsore on and off. I also have this constant bad breath--my husband made acomment the other day, so I’ve been brushing my teeth and chewing on gum more lately.

Doctor: And how would you describe the pain?
Richa: Sort of like a burning/stabbing sensation.

Doctor: And once it starts each night, how long does it usually last?
Richa: About 30 minutes to an hour, but sometimes longer.

Doctor: Is there anything that you’ve noticed makes it worse?
Richa: Generally when I eat a lot or it’s really spicy, it’s worse than usual.
