Insulin, produced by the pancreas, enables the body to take up and use glucose sugar from the blood. Diabetics have an inability to take up glucose from the blood and can have high blood sugar, which is easily fixed by administering insulin.

Ensure your blood sugar is above 72mg/dL before taking insulin, especially if you're on insulin. If insulin-resistant, lifestyle changes and medications may be necessary; consult your diabetes team. Medication adherence is crucial; consult your doctor before stopping any medication. Prediabetes indicates higher-than-normal blood sugar but not diabetes; monitor levels closely. Aim for a fasting blood sugar level below 99mg/dL for optimal health.

Insulin helps break down sugar into energy. Diabetes effects insulin, whether it can't produce insulin, or the insulin it makes is not effective. This means that when you put in sugar, it just builds up, creating high blood sugar. You do need some blood sugar in your body, so you take in sugar. The basic answer is this: sugar in moderation.
Your blood sugar drops. Assuming you are a diabetic, which would be the only reason you would take insulin, your blood sugar would go down. If you aren't a diabetic and you are taking insulin this could drop your blood sugar to dangerous levels. Causing you to pass out.
You have not yet asked a question. When a person is diabetic, their body loses the ability to make insulin to balance their blood sugar, and may need to take insulin. If there is too much insulin, and their blood sugar is low, they may drink orange juice to quickly raise their blood sugar level.
Insulin
You should first check your blood sugar, then give yourself the appropriate ammount of insulin to lower your blood sugar down into the normal range. If your blood sugar just isn't going down then you should check for keytones. You can usually find the keytone strips at a pharmacy. If you do find out that you have some keytones then call your endocrinologist, and then just follow his/her instructions. If your ever in doubt call your endocrinologist's office and they should answer any questions you may have.
