What Is Stress?
Stress is your body's response to a challenging or demanding situation. When you feel stressed, your body releases certain hormones. Your hormones are chemical signals your body uses to tell your body systems what to do. The hormones your body releases when you're stressed get you ready to meet the challenge or demand in your environment. During the stress response, your body gets ready to flee or fight by increasing your heart rate, breathing rate, and blood pressure.
Not all stress is bad. In small doses, stress can help you accomplish tasks or prevent you from getting hurt. For example, stress is what makes you slam on the brakes to avoid hitting a suddenly stopped car in front of you. That's a good thing.
But people handle stressful situations differently. What stresses you out may be of little concern to someone else.
Stress can be a short-term response to something that happens once or only a few times or a long-term response to something that keeps happening. Our bodies can usually handle short-term stress without long-term effects. But long-term or chronic stress can make you sick, both mentally and physically.
The first step to managing your stress is to know the symptoms. But recognizing stress symptoms may be harder than you think. Many of us are so used to feeling stressed that we may not know it until we get sick. Read on to learn more about the various symptoms you may have when you're stressed.
Difference between stress and distress
Stress is a normal reaction to challenges in your physical environment or in your perceptions of what's happening around you. Experts consider distress to be stress that is severe, prolonged, or both. Distress is when you feel you’re under more stress than you can handle.

- Depression
- Substance use disorder
- Disordered eating
It may be time to visit your doctor if you're struggling to cope with the stress in your life or you have mental health problems from long-term stress. They can help you figure out ways of coping in a healthy way or refer you to a mental health professional who can help you.
Posttraumatic Stress Disorder
Posttraumatic stress disorder (PTSD) is mental health condition that you may have after you have or witness a traumatic event, such as a natural disaster, accident, or violence. PTSD overwhelms your ability to cope with new stress. PTSD can lead to symptoms such as intrusive memories, avoidance behaviors, and hyperarousal.
These symptoms can cause significant problems in your work or relationships. Talk to your doctor or a mental health professional if you've had or witnessed a traumatic event and have disturbing thoughts and feelings about it for more than a month, if your thoughts and feelings are severe, or if you feel like you're having trouble getting your life back on track.
What Are the Consequences of Long-Term Stress?
Ongoing, chronic stress can trigger or worsen many serious health problems, including:
- Mental health problems, such as depression, anxiety, and personality disorders
- Cardiovascular disease, including heart disease, high blood pressure, abnormal heart rhythms, heart attacks, and strokes
- Obesity and other eating disorders
- Menstrual problems
- Sexual dysfunction, such as impotence and premature ejaculation in men and loss of sexual desire in men and women
- Skin and hair problems, such as acne, psoriasis, and eczema, and permanent hair loss
- Gastrointestinal problems, such as GERD, gastritis, ulcerative colitis, and irritable bowel syndrome

Stress FAQs
What can extreme stress cause?
Extreme stress, especially if it's prolonged, can cause emotional distress. And stress from a traumatic event, which is usually extreme, can cause posttraumatic stress disorder (PTSD). These are more serious cases of stress that overwhelm your ability to manage on your own. You may need to get a professional's help to get back on track. If you feel like you're having trouble managing your emotions, talk to your doctor. They can help you or direct you to someone who can help you.
Can stress make you throw up?
Yes, stress can make you throw up. Your digestive system is one of the many systems that stress can affect. In fact, you may have a whole range of other digestive symptoms, such as nausea, pain, and constipation or diarrhea. Not everyone has stress nausea or vomiting, but you may be more prone to it if you have a gastrointestinal condition, such as irritable bowel syndrome (IBS), or you have anxiety or depression.
You may be able to tell if you're stress vomiting if your episode passes when the stress goes away. If it doesn't, then your episode may be caused by something else. It's time to get checked out by your doctor if you have more than a couple of episodes or you can't figure out what's causing them.
