In addition to being overweight, there are other possible triggers of laminitis. We list what you should look out for...
- A dietary ‘insult’ that has changed the fermentation in your horse’s hind gut (eg a very large meal of starch)
- Badly shod feet, uneven weight bearing, or repetitive trotting on hard ground. These all affect blood flow to the foot over time. Traumatic causes could be thought of as being similar to persistently hitting your thumb with a hammer, and the resultant blood blister and inflammation; mechanical causes could be thought of as similar to getting pins and needles because
of ill-fitting shoes
- Starch overload, post-colic surgery and liver problems which all cause inflammation in the body. This may result in endotoxaemia, which affects blood flow rapidly, often within 12 to 48 hours – the onset of laminitis is then dramatic and sudden
- Physiological stress caused by being cold or in pain. Latest research suggests laminitis is strongly connected with hormones. If a horse or pony is under stress, his cortisol levels go up, and this rise, over a long period, can cause insulin resistance. This, together with him being ‘comfortably cuddly’ will make him more susceptible to laminitis
