Alexandra, without getting too high complex, type 2 diabetics develop insulin resistance as their target organs repond less and less to insulin (less uptake of glucose by various organs), thus keeping serum glucose levels way higher. This certainly happens over quite a duration. I don't know the exact pathophys. of how obesity directly increases insulin resistance or leads to development of DM2, but we know that adipocytes have endocrinologic factors that likely play a role in this. In non-insulin dep. DM2, we have various agents that can either increase the secretion of insulin by the pancreas or more novel agents which also have the capacity to decrease end-organ insulin resistance, i.e. make target organs more sensitive to insulin.

The most likely diagnosis is:

The most likely diagnosis is:?
19: A 30-year-old nursing student presents with confusion, sweating, hunger, and fatigue. Blood sugar is noted to be 40 mg/dL. The patient has no history of diabetes mellitus, although her sister is an insulin-dependent diabetic. The patient has had several similar episodes over the past year, all occurring just prior to reporting for work in the early morning. On this evaluation, the patient is found to have high insulin levels and a low C peptide level. The most likely diagnosis is: a. Reactive hypoglycemia b. Early diabetes mellitus c. Factitious hypoglycaemia d. Hepatoma e. Insulinoma

I'm no doctor but... Have you checked to see if the patient is suffering form starvation or malnutriton syndrome? It's overlooked you know. http://healthresources.caremark.com/topic/topic100587123

I'm going with c. Endogenous insulin (from a. and e.) would have the c-peptide. The fact that there is no C-peptide means that the insulin comes from outside her body. c. is the only such choice. One hint is that her sister uses insulin; the patient would have access to insulin from her. Another hint is the timing: "just before work". That is consistent with factitious illness. Note that a. (reactive) would use pancreatic islet insulin, and so have c-peptide. Also, e. (insulinoma-produced) insulin has c-peptide: http://www.emedicine.com/med/topic2677.htm Choice b. would have low insulin levels, and choice d. (hepatoma) is irrelevant to glucose homeostasis.
5 :
Confusion, sweating, hunger, and fatigue are all classic symptoms of hypogycemia, and this is verified by blood sugar of 40mg/dL (normal is 70-120 mg/dL). High insulin levels would result in low blood sugar since effect of insulin is uptake of glucose from bloodstream by muscle and liver cells. Insulinomas (tumors of the islet cells in the pancreas that can produce uncontrolled amounts of insulin and C-peptide) can be eliminated since there are low C peptide levels. C peptide levels should mirror insulin levels, therefore if person has high insulin production they should have high C peptide levels (low C peptide = low insulin). Hepatomas are liver cancers, and this should be eliminated since sugar uptake is fine (liver cells can uptake glucose). The pancreas is the organ that secretes insulin and glucagon, so again another reason to eliminate. Factitious hypoglycaemia is the result of the patient inducing hypoglycemic conditions thru ingestion of insulin or other hypoglycemic agents. Thismeans that the student deliberately induced the hypoglycemic condition...need more psych eval to determine. Reactive hypoglycemia is a medical term describing recurrent episodes of symptomatic hypoglycemia occurring 2-4 hours after a high carbohydrate meal (http://en.wikipedia.org/wiki/Reactive_hypoglycemia). I would eliminate since I doubt student awoke 2-4 hrs before early-morning shift to eat. Early DM can be diagnosed by blood sugar and C peptide levels, which should show both levels high. This leaves us with factitious hypogycemia....student is ingesting/injecting insulin to induce hypoglycemia. She is busted since her C-peptide levels are low!

To clarify my question about being behind on house payments

To clarify my question about being behind on house payments:?
I seemed to have given you people the wrong impression about myself. I sold my home 2 years ago to move in with them to take care of my 3 grandchildren and do household and laundry chores while my son-in-law and daughter work outside the home. I was diagnosed last year with cancer of the eye, diabetes mellitus, rheumatoid arthritis, and COPD to name just a few of my health problems. However, I am still caring for the children and doing my daily chores. I have applied for disability but it has not been settled yet. I have no money at this time as I helped them get into this new house with the money I had when I sold my own home. So please understand I am not a freeloader by any means. I just used the term our house because I live here. It really is not my house. Some of the answers below have been pretty mean-spirited and not very helpful. Get rid of all your sarcasim and pointing the finger at me and just answer my question. I really need some good advice right now.

I didn't see your other question but, i would guess they are behind in payments...Now with what you have listed you will get disability and back paid from the date of your application...Now this could take 6 months to a year...What your doing for your family is saving them a lot of money...If there are issues with the house payments, refinancing may help and cutting back on things really not needed to survive...
