I am young,healthy weight,didn鈥檛 lose weight since excessive thirst but could I still have diabetes?

I pee a lot more,and I'm really thirsty...I sometimes have nausea and minor headaches,and I feel tired(although when I sleep well,IN THE EVENING I'm kinda "hyperactive").I don't pee to the point of waking up at night though.I didn't really lose weight,I did gain some but I can explain it,coz I'm eating way more than I did before(well,for 3months or so I ate very little and exercised a lot,so I lost weight,and now I gained most of it back),so yea it is kinda expected.But I still never been overweight,I just always was a bit chubby,on the healthy weight range.I do eat quite some sugar,but I'm always running on the stairs,and exercise for AT LEAST twice a week.None of my parents have diabetes,none of my aunts and uncles,none of my cousins,but my grandma does,and she had it at an old age,so yea,it's kind of common.I'm so extremely scared and I don't ever drink soda since a year ago,I don't add sugar to tea or coffee,but I eat lots of chocolate,sweets,fruit.I am turning 14next month

You may be at risk. The internet is not a good place for medical diagnosis. Diabetes can only be diagnosed by a doctor. Eating chocolate and sweets will not create diabetes but if you are diabetic then they can greatly aggravate the condition.
excercise is good..follow a good diet with fruits and veggies (not fried) and a very limited amount of meat..this is good whether or not you are diabetic. Type II diabetes often de velops over a period of years so you could be "pre-diabetic" even if no one in your family has a history of it. There is an inexpensive test available at large pharmacies...the a1c test. It measures the average glucose in your system for the past 3 months. There is a "strip test" with a meter but that is not unless you know you have diabetes and can be prescribed by a doctor. The a1c is at my local walmart for $8.... follow directions carefully read them until you are SURE you understand....the test requires a 12 hour fast(nothing to eat for 12 hours) best done overnight...do not eat anything (you can drink water) after supper and test before breakfast the next day. The test will give a number...
any where from 5 to 7 is normal with 6 being the best..if you are near the high or low end see a doctor and get a better test. I am glad you are concerned about this even though you do not seem to be a HIGH risk. Better to check it out..Someday a test like this will be given in school (like the patch test etc) Good luck and remember this is only a suggestion...if you are really concerned see a doctor.

Avoid sugar and high amounts of carbohydrates. Eat balanced meals with whole grains at regular times. Losing weight helps control diabetes.
Check your blood sugar.

I would say you could be at risk for Thyroid too. I worked out hard and lost 35 pounds over a summer. But i just couldnt lose anymore, I went to the doctor and he said i was diabetic and had hypothyroidism (which has some the same symptoms as diabetes). He had said losing weight so fast over 2 months could of triggered the thyroid but could of been cause the diabetes. How often are you going to the bathroom? How much water do you drink a day? Is it possible you could be pregnant?
