Other types of diabetes

Maturity onset diabetes of the young (MODY)

A relatively rare form of diabetes, MODY is caused by a mutation in a single gene. Someone with a parent who has the gene has a 50 per cent chance of inheriting the condition. A child who inherits the mutation will have a higher probability of developing MODY before the age of 25.

Gestational diabetes

This form of diabetes affects women during pregnancy. Hormones produced at this time can make it difficult for the expectant woman’s body to use insulin effectively. This puts her at increased risk of insulin resistance. Some women cannot produce enough insulin to overcome the resistance because of the demands pregnancy puts on the body. Glucose is not used properly for energy and levels rise as glucose remains in the blood.

Factors putting women at increased risk of Gestational diabetes include being overweight or obese, having already had gestational diabetes during a previous pregnancy, having had a very large baby previously, having a parent or sibling with diabetes or being of South Asian, African Caribbean or Middle Eastern background.

Neonatal diabetes

It is babies under the age of five months who are diagnosed with neonatal diabetes. It is caused by a gene change which affects insulin production, leading to very high levels of blood glucose. It is extremely rare, with only around 100 people currently diagnosed with it in the UK.
