Type 2 & other diabetes

Glucagon and beta-cell function changes before and after dietary weight loss-induced metabolic improvements in type 2 diabetes

Diabetes Res Clin PractPublished Prospective interventional study

Authors' conclusion

Weight loss > 10% improved insulin sensitivity and beta-cell function relative to baseline and normalized glucagon in participants with initial hyperglucagonemia.

Study context

Population
Patients with T2D treated without insulin achieving >10 kg weight loss on a 12-week VLCDachieved >10 kg weight loss
Participants
35 patients
Exposure
Before vs after 12-week VLCD
Outcome

  • Before-after

Main finding

As reported in the abstract

Beta-cell glucose sensitivity improved
p = 0.001
Insulin clearance improved
p < 0.001

Observational data: associations, not effects.

Further findings

Fasting glucagon by baseline glucagon (above vs below median)

Fasting glucagon decreased significantly only in participants above median glucagon level
P = 0.001
Changes in insulin sensitivity and beta-cell glucose sensitivity did not differ between groups
Postprandial insulin secretion decreased and potentiation factor increased only in the higher glucagon group

Determinants of fasting hyperglucagonemia

Fasting hyperglucagonemia was associated with male sex
