 ==Diagnosing Carbohydrate Deficiency==
-If there is low to absent carbohydrate intake with insufficient hepatic gluconeogenesis, clinical signs of hypoglycemia can occur (such as lethargy and seizures). Blood glucose concentrations below the normal laboratory reference interval will be seen on serum biochemistry profiles.
+If there is low to absent carbohydrate intake with insufficient hepatic gluconeogenesis, clinical signs of hypoglycemia can occur (such as lethargy and [[seizures]]). Blood glucose concentrations below the normal laboratory reference interval will be seen on serum biochemistry profiles.
 Animals consuming inadequate dietary fibre may exhibit signs of colitis (e.g. tenesmus, hematochezia, mucousy loose stool, increased frequency of defecation), that resolves with addition of fibre to the diet.

 ==Dietary Sources==
-Dietary carbohydrates (both absorbable and non-absorbable) are primarily found in '''fruits, vegetables, cereal grains, and pulses '''(i.e., legumes). Animal sourced carbohydrates (glycogen) are also found in '''muscle and liver'''.
