HGV Medical Diabetes Explained 

What is HGV Medical Diabetes?

Diabetes is when the body is no longer able to process sugar properly. This causes a build-up of sugar in the blood. The sugar then can cause damage to different parts of the body.

There are 2 types of diabetes:

  1. Type 1
  2. Type 2

Type 2 diabetes

This is when the body fails to produce insulin, the hormone responsible for managing sugar levels. This is normally treated by replacing insulin itself in the form of injections.

Type 2 Diabetes

This is normally developed later in life. Here, your body does not react to insulin properly. Therefore, causing your blood sugars to rise. This is normally treated with medication.

DVSA requirements for diabetes

The requirements for the DVLA depends on what medication you take.

Medication that need blood sugar monitoring

If you are taking medication which can cause you to have a low blood sugar, you need to monitor your blood sugars.

These medications include:

  1. Insulin
  2. Sulphonylureas – E.g. Gliclazide, Glipizide, Glimepiride and Tolbutamide
  3. Glinides – E.g Repaglinide and Nateglinide

If you are taking other medications like Metformin, Sitagliptin or Dapagliflozin, the DVLA do not legislate checking your blood sugars. Although, it is still recommended to monitor your blood sugars regularly, if you feel unwell or if you are starting a long journey.
