Geriatric Weight Loss & Muscle Wasting (Sarcopenia)
Many older horses lose weight and especially muscle (sarcopenia) over time, particularly over the topline and hindquarters. This is almost always multifactorial — tooth wear, hormonal changes (PPID), declining feed utilisation, pain or competition in the herd act together. Weight loss in old age is not a normal part of ageing but a reason to look specifically for the causes.
Veterinary care required
This condition belongs in veterinary diagnosis and treatment. Compounds are at most supportive.
Priority · vet & management
The focus is on veterinary investigation of the cause — dental check, blood count, ACTH if PPID is suspected, fecal exam and a pain check — not simply feeding more. On this basis follow a needs-based, well-digestible (often soaked) ration, a separate quiet feeding place and regular weight monitoring (BCS, weight tape). Complementary feeds are only adjunctive.
Possible causes
- · dental problems with poor grinding (tooth wear, gaps, EOTRH, sharp edges)
- · PPID (Cushing) and age-related hormonal/metabolic changes
- · declining digestive and protein utilisation as well as increased maintenance/protein demand in old age
- · chronic pain (e.g. osteoarthritis), parasite burden or a low-ranking position at the feeding place

Regular senior checks (teeth, weight/BCS, ACTH if suspected) and adapted feeding/housing management detect beginning decline early, before it determines the general condition.
Equiterna's take
Equiterna understands geriatric weight loss as a leading symptom, not a diagnosis: behind it there are almost always several causes at the same time. The first step is the veterinary work-up — feeding follows the diagnosis, not the other way round.
