Does a low carbohydrate diet cause darkening of the skin?

Hi doctor, my son, age 43, has changed his diet and his exercise. He now eats large salads for lunch and supper. He limits sweets and he limits carbs like cereal and bread products. I noticed this week that his skin is quite a bit darker than usual, and it has a yellow tinge to it. Can this be related to his new diet ? He has been doing this for 18 months now.......

Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.

I think the darker skin and yellow tinge are not related to vegetable and full grains. I think he is suffering from hiperbilirubinemia which gives yellow color to skin.
The causes of hiperbilirubinemia are:
*Hepatitis A,B,C D,,E, cirrhosis
*Gallbladder stones and colangitis
*Cancer of liver or gallbladder
*Pancreatitis or cancer of pancreas head
*Some medications and autoimmune disease.

I recommend him to do:
*AST, ALT,bilirubin direct and indirect.
*total blood count.

Hope I have answered your query.
Let me know if I can assist you further.

After my workouts I get a sweet taste in my mouth should I be worried or is it just my ketone levels raising from a low carb diet. (I am trying to cut, and define my body more so I am staying away from carbs as much as possible) is this damaging my body in any way, should I up my carb intake a little to stop this?

Hi. My wife is 22 weeks pregnant and was diagnosed with pre diabetes 4 years ago. There is a high rate of diabetes in her familly. She has been on a carb restricted diet since her diagnosis. She used to test her blood sugar with a monitor on a regular basis but, thinking that she had it under control with diet, stopped doing so quite a while ago. However, last week, she tetsted her BS 2 hours post prandial and got an alarmingly high reading of 10.2mmol/l. She arranged for a glucose challenge test and failed with a 10.9. (8.3 being the cut off at this hospital) She then did the 3 hour test and got the following results : 5.6, 8.9, 7.9, 6.8 and was told that she had not blood sugar problems. Knowing that that she quite obviously HAS high BS, this was a rediculous result, so I did a little research and found that, for this test to be accurate, the person being tested must have been eating a normal diet for at least three days before the test. Her carb restricted diet must therefore been the reason for her passing the test. You may well be wondering why the maternity unit taking care of her during her pregnancy was not taking care of her high risk condition as a pre diabetic, but we have just found out that her midwife mistakenly never put it on her chart during their first meeting. Even though we told the hospital that she was in fact on a carb restricted diet before the OGTT, they still insist that she does not have diabetic issues because that test is the gold standard and if she passed that she is! To make matters worse and more infuriating, we went to our local GP for a second opinion. She said that we shouldn t worry because it is normal for people to get blood sugar spikes over 10 even without diabetes.....???!!! She even advised my wife not to check blood sugar with the monitor at all because it would only cause worry and be dangerous for her pregnancy. We are at our wits end......please advise. Thank you in advance.

So I have had a twitch for about 6 days or so in my bottom right lip area (not on lip, but area under lip and close to right side of chin ..... had it one time before about a year ago, and it last for about 7-10 days....feels like a slight jumping nerve. I am nervous about it, and I have no other symptoms of anything, as I am in good health. I eat a low carb diet , drink diet sodas, and salty foods. Any feedback?
