Abstract:
Carbohydrate restriction is not typically recommended for children with type 1 diabetes mellitus (T1DM) because of concerns regarding growth retardation, ketoacidosis, severe hypoglycemia, and dyslipidemia. There is no consensus regarding the effects of carbohydrate restriction on the growth of children with T1DM. However, some previously reported cases of T1DM exhibited growth retardation during carbohydrate restriction, whereas others showed no obvious impairment. A female child with T1DM exhibited severe height growth velocity impairment during carbohydrate restriction in early childhood. Her height standard deviation score (SDS) was 1.12 at the initial T1DM diagnosis (2 yr and 11 mo of age) and -1.33 at 4 yr and 8 mo of age. Her height velocity was only 1.7 cm/yr (SDS -7.02). Discontinuing carbohydrate restriction substantially improved her height growth velocity. Implementing a carbohydrate-restricted diet in children with T1DM can negatively affect height growth velocity.

Diabetes Mellitus: Overview and Type I Subtype
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
