The main hormone in the blood is adrenaline. We already know that it can help us in motivation, but the excess can leave sequelae in the body, as well as cortisol, another hormone released by the body to face situations interpreted as dangerous. The latter, if produced frequently or is very long lasting, can affect the immune system, which can cause changes in a person's body. That is, stress can cause serious physiological effects, such as reduced immunity, heart disease, obesity, among others.
Answer: Chronic stress-hormone induced physical changes can also increase people's appetite, causing them to gain weight and potentially, to become obese. Obesity puts individuals at risk for developing other health problems such as diabetes, heart disease, strokes, and arthritis.
