- Gas Accumulation: Bloating often results from excessive gas buildup in the digestive system. This can occur when an animal eats too quickly, gulps air while eating, or consumes foods that are difficult to digest, such as certain plants or legumes.
- Rapid fermentation: Some animals, like cattle, have a four-chambered stomach, and when they ingest large quantities of easily fermentable carbohydrates (such as grains or lush pasture), the microbes in their rumen rapidly ferment the food, producing large amounts of gas.
- Obstruction: Bloating can also be caused by an obstruction or blockage in the digestive tract. This can be due to foreign objects (like plastic or fabric), hairballs, or even tumors that prevent the passage of gas and food.
- Infections: Certain infections or diseases, such as bacterial overgrowth or certain types of parasites, can disrupt the normal digestive process and lead to bloating.
- Trauma: Severe physical trauma or injuries to the abdominal region can cause tissue damage and disrupt normal digestive function, leading to bloating.
- Organ Failure: In some cases, bloating can be a symptom of underlying organ failure, such as liver or kidney problems, that affect fluid balance and digestion.
