II diabetes, why exercise, control your diet and control

For Type II diabetes, why exercise, control your diet and control your body weight are important?I know that you should not take too much sugar or starch, but besides that, would controlling your diet eventually help you get cured, I mean become normal, no longer need medicine?To my understanding that type II diabetes is caused by nit enough insulin produced or your cells are not listening to the signal that insulin told them to uptake the glucose in your blood, why exercise could possibly change this? Would exercise make your pancreas to secrete more insulin, or to make your cells to start in-taking glucose?Similarly for the weight control, if you're not very much over weighted, would controlling weight have an effect on insulin level or on cells' glucose intake level?

Can someone help me understand what happened? I never get

Hello, can someone help me understand what happened? I never get pale. I have history of ms and sarcoidosis. Last night I was really - REALLY nauseated. I thought it was from eating too much cheese at school with friends (in np program and we all brought diff kinds of cheese and fruit), and were at lab all day. This am woke up better, nausea onset an hour after I woke up. Then I started feeling like room was spinning, had 4 bowel movements in a row, and chills. My husband said I looked very pale. Checked my bp- if anything it was higher than normal. Can you tell me why I would be pale with normal bp. Should I be concerned? What does this sound like? I will attach a pic of me, I don't think I looked pale- but figure it can help. Sorry I looks So rough. As a side note, I haven't been getting enough sleep

I am having an issue. I did cocaine (not that much, a few

Hello. I am having an issue. I did cocaine (not that much, a few key bumps ) on New Years. I officially stopped around 3 am January 1. But I'm worried because I drank as well. I have a saliva test tomorrow, Friday morning. Once again, I did cocaine and drank on saturday night/early Sunday morning. I have a test Friday morning tomorrow. I know metabolites take longer and such. Will I show up positive? I haven't had an alcoholic beverage (except a small glass of wine) within that time frame. I'm drinking a lot of fluids. I'm about to buy an at home urine test from the store but I'm not sure if the at home kits show the presence of the cocaine metabolite. Please help!!!JA: Is this a time sensitive issue? What type of specimen are they testing?Customer: Saliva / oral swab. It is very time sensitive I have until tomorrow morningJA: Anything else in your medical history you think the doctor should know?Customer: No

HelloThe other day I was cleaning the insides out of a frozen turkey and my hands got extremely cold from the ice. I immediately had a little chest pain lasting a few minutes. I have had this symptom once before when handling ice. Just an FYI, I recently had a stress echo which was normal. This was done for tachycardia.. I also have Fibromyaglia and tend to have a little bit of Raynauds in fingers and toes. Just slightly.

I have a question that is specific to a GI specialist...

I have a question that is specific to a GI specialist...For a year my 19 year old son has been dealing with IBS mixed D/C as well as GERD which is the more bothersome of the 2 as it has caused a feeling of phlegm and/or lump in his throat. For the IBS, He follows the FODMAP recommendations for his diet and it has helped the IBS. He takes Align daily and Protonix 40mg daily. The reflux symptoms are worsening now despite taking Protonix. He has been tested for Celiac, and H Pylori. He has had an endoscopy which was normal. All blood tests have been normal.What more can we be asking his doctor and/or what more can we do to improve his symptoms or better yet cure whatever is causing all this?

Dear Doctors, I am a first year international biology student.

Dear Doctors,I am a first year international biology student. I have a question, what I amtrying to figure out. If anyone could help me understand this I would greatlyappreciate it.Question1: Metyrapone testNormally the metyrapone test will cause the deoxycortisol levels to rise, butin cases of Cushing's syndrome they may not. What does this failure to respond inthe metyrapone test indicate about ACTH secretion and what might cause thisThank you.Sincerely,Evafailure?Question 2: Dexamethasone Suppression test:I know that in patients suffering from depression very often the low dose treatment has no effect, while the high dose suppresses cortisol secretion. In some, but not all forms of Cushing's syndrome, both low and high dose of treatments fail to bring cortisol down. But, what do these varying response patterns tell me about what is happening to control of the adrenal in these different disease states, and why do some Cushion's syndrome patients respond to high dose of dexamethasone, but others do not?
