Why Can’t Dogs Eat Before Surgery?

If your furry friend is scheduled for surgery, you may be wondering why they are required to fast before the procedure. It is a common practice for veterinarians to ask pet owners to withhold food for a certain period before surgery. This article will explore the reasons behind this precautionary measure and answer some frequently asked questions related to the topic.

When a dog is scheduled for surgery, whether it is a routine procedure or a more complicated one, fasting is essential to minimize the risks associated with anesthesia. Here are the primary reasons why dogs cannot eat before surgery:

1. Aspiration risk: Anesthesia can cause a dog’s gag reflex to be suppressed, making it difficult for them to protect their airway. If a dog vomits while under anesthesia, there is a risk of inhaling the vomitus into their lungs, leading to a potentially serious condition called aspiration pneumonia. Fasting helps reduce the chances of vomiting during surgery.

2. Anesthetic drug interactions: Some medications used during surgery can interact with food in the stomach, affecting their absorption and metabolism. Fasting ensures that the drugs are administered and metabolized properly, reducing the risk of complications.

3. Delayed gastric emptying: Food in the stomach can delay the passage of gastric contents into the intestines. This delay can lead to an increased risk of vomiting during or after surgery, as well as a potential obstruction or complication during the procedure.

4. Preventing regurgitation: Regurgitation occurs when stomach contents flow back up into the esophagus, often due to pressure on the abdomen during surgery. If a dog has recently eaten, regurgitation can lead to aspiration, as the food may enter the airway.

5. Accurate monitoring: Fasting ensures that a dog’s stomach is empty, making it easier for the veterinarian to monitor vital signs, such as heart rate, blood pressure, and temperature during surgery.
