Is my leopard gecko impacted?
Impaction is a blockage of the gut, usually from swallowed loose substrate or prey that's too big or hard-shelled to pass. The signs are a gecko that stops passing waste, goes off its food, turns lethargic, strains without result, or shows a dark mass through the belly, and because cool temperatures slow the gut, the first thing to confirm is that the warm hide is actually warm enough.
What causes impaction
Impaction happens when something in the gut can't move through. The two usual causes are ingesting loose particulate substrate, sand, fine gravel, walnut shell and the like, often swallowed accidentally while grabbing prey, and feeding items that are too large or too hard-shelled, such as oversized mealworms or superworms. A good size rule is nothing wider than the space between the gecko's eyes. A too-cool warm end makes it worse, because a gecko that can't get warm can't digest what it eats.
The signs to watch for
A suspected impaction shows as no waste being passed for an unusually long stretch, loss of appetite, and growing lethargy. You may see a firm, dark mass through the skin of the belly, and the gecko may strain or push without producing anything. It can also lose interest in movement and sit hunched. Any of these on their own is worth watching; several together point strongly to a blockage that needs acting on.
Check the warm end first
Before assuming the worst, rule out simple cold. Leopard geckos digest through belly heat, and a warm hide that's drifted below about 28–32°C (82–90°F) slows the gut so much that waste backs up even without a true blockage. Measure at floor level with a digital probe, not a stick-on dial, and correct the mat, bulb or thermostat if it's cool. Sometimes restoring proper warmth is all it takes for things to start moving again.
What you can and can't do at home
For a mild case, once the warm end is confirmed correct, a shallow lukewarm soak for ten to fifteen minutes with a very gentle belly massage towards the vent can sometimes help things pass. But a genuine impaction is a veterinary matter, not a home fix, never give oils, mineral oil, laxatives or force anything, as the wrong treatment can do real harm. If soaking and correct temperatures don't produce a result quickly, or the gecko is lethargic and off its food, it needs a vet.
When to see a vet
See an exotics vet if the gecko hasn't passed waste over an extended period, is straining without result, shows a firm dark mass through the belly, or is lethargic and refusing food, especially if a warm soak and correct warm-end temperatures don't get things moving. Don't give oils or laxatives at home; real impaction needs veterinary assessment.
One reading rarely tells the story. What matters is whether it's an isolated blip or part of a trend, so look at recent weight, feeding intervals, shedding, temperature and behaviour together.
baskr keeps those records in one place and watches the pattern for you, so you can see whether something has genuinely changed with your leopard gecko, before it becomes a problem.

What are the signs of impaction in a leopard gecko?+
No waste passed for an unusually long time, loss of appetite, lethargy, straining without result, and sometimes a firm dark mass visible through the belly. Several of these together point to a blockage, confirm the warm end is warm enough, then see a vet if it doesn't clear.
What causes impaction in leopard geckos?+
Usually swallowed loose particulate substrate such as sand or fine gravel, or prey that's too large or hard-shelled. A too-cool warm hide makes it worse by slowing digestion. Feed prey no wider than the gap between the gecko's eyes and keep the warm end at 28–32°C (82–90°F).
Will a warm bath help my impacted leopard gecko?+
For a mild case on a correct warm end, a shallow lukewarm soak of ten to fifteen minutes with a gentle belly massage can sometimes help things pass. A genuine impaction won't clear this way and needs a vet, never use oils or laxatives at home.
Can impaction kill a leopard gecko?+
Yes, a full blockage stops the gut, kills the appetite and can become life-threatening if left. That's why real impaction is a veterinary matter rather than something to keep treating at home, and why prompt vet care matters once simple warmth and a soak haven't worked.
