Weight loss: overview

icanis

Introduction

  • Weight loss occurs when calorie expenditure exceeds intake for a duration that exceeds the capacity of the body's normal compensating mechanisms.
  • Clinically significant weight loss exists when there is a reduction in body weight of 8-10% not explained by obvious historical factors, eg dehydration.
  • Assess the optimum weight of a dog by reference to published breed averages for pure breeds. Assess cross-breeds in relation to pure breeds of similar size and stature.
  • Body condition scoring Body condition scores is an accurate method of assessing animals in the clinical situation. It takes account of individual variations in stature within breed groups.
  • Ideally, the same person should carry out sequential condition score assessments.
  • Accurate, properly calibrated scales are essential for monitoring suspected weight loss. Measure once/twice a week on the same scales.
  • Weight charts, histograms or graphs are useful for monitoring chronic cases.
    Many clinical data entry programs have this facility.
