Hypokalemia is a low level of potassium (K +) in the blood serum. [1] Mild low potassium does not typically cause symptoms. [3] Symptoms may include feeling tired, leg cramps, weakness, and constipation. [1] Low potassium also increases the risk of an abnormal heart rhythm, which is often too slow and can cause cardiac arrest. [1] [3]
Orthopedic causes of lameness are very common and may be the result of damage to the hoof, bone, joints, or soft tissue. Horses are predisposed to orthopedic lameness by conformational flaws, poor hoof balance, working on poor footing, repetitive movements, poor conditioning for a given activity, and competing at a very high athletic level.

Horses with ID will have an increased insulin response after they are given oral sugars, which will cause a subsequent rise in blood insulin levels, or hyperinsulinemia. Hyperinsulinemia results in decreased tissue sensitivity to insulin, or insulin resistance especially by the skeletal muscle, liver and adipose tissue.
Low potassium is caused by increased excretion of potassium, decreased consumption of potassium rich foods, movement of potassium into the cells, or certain endocrine diseases. [3] Excretion is the most common cause of hypokalemia and can be caused by diuretic use, metabolic acidosis , diabetic ketoacidosis , hyperaldosteronism , and renal ...
[2] [3] A chemistry panel will often show electrolyte abnormalities (hypokalemia, hyponatremia, hypochloremia) due to electrolyte loss into the lumen of the intestine. Leukocytes may be normal, increased, or decreased. PCV and total protein are usually both increased due to fluid loss, and the horse displays a prerenal azotemia. [2]
Lameness in horses has a variety of causes, and treatment must be tailored to the type and degree of injury, as well as the financial capabilities of the owner. Treatment may be applied locally, systemically, or intralesionally, and the strategy for treatment may change as healing progresses.
Beyond the probable hereditary factor, no other single cause is known to trigger ER in horses. Due to the "Exertional" component, exercise is seen in every case of ER regardless of type and severity. However, exercise cannot alone be the singular cause of ER, rather it is always accompanied by another factor.
As horses become older, the cannon bone becomes stiffer and thus bucked shins rarely occur again. Approximately 12% of horses that develop bucked shins go on to have stress or saucer fractures later. [46] Bucked shins force 7% of racehorses to retire. [47] Splints are new bone formation (exostoses) along the involved splint bone. [48]
