What Is the Temperature of the Inside of a Human Stomach?

The temperature in the human stomach would be around 99.6 degrees Fahrenheit or 37.6 degrees Celsius. This is also known as the core body temperature and is usually measured rectally. Core body temperature is the most accurate and relevant source for measuring temperature.

The stomach is located in the area of the body known as the core. Measuring temperature in this region gives an internal reading that is medically preferred over the external reading taken from the axillary region, or the armpit. Ranges for temperature vary in every human and can be affected by many factors, including stress, illness, metabolism and elevated heart rate.
