You Could Be Pregnant
Thanks to the tropes of movies and TV shows, many people are well aware that sudden nausea may be a symptom of pregnancy. Its true that pregnancy particularly early pregnancy can cause nausea. Although its often referred to as morning sickness, it can in fact happen at any time of day. There is no singular cause of nausea during pregnancy, but common causes include an increase in hormones, as well as reduced blood sugar. Symptoms usually start before nine weeks of pregnancy and for most women, nausea goes away by the 14th week. For some, however, nausea can last for several weeks or months and for a few, it can last throughout the entire pregnancy. In up to three percent of pregnancies, a condition called hyperemesis gravidarum can occur. This is a severe form of nausea and vomiting that can cause dehydration and other complications, so it requires medical treatment. While mild nausea and occasional vomiting in early pregnancy arent necessarily dangerous, you should talk with your care team if the symptoms are causing you concern, causing difficulty with keeping fluids down, or negatively impacting your daily life. New onset nausea and vomiting in late pregnancy can be a sign of serious pregnancy complications, so be sure to contact your provider urgently if this occurs.

A Natural Part Of The Fight
Anxiety is a natural reaction, and in small doses, its actually healthy. It is thought that some of the symptoms of anxiety including nausea developed to tell your brain that there was something dangerous or new in the vicinity so that you would make a smart decision regarding your next action.
When you are under stress but not facing any present danger, nausea can be especially distressing. When faced with stress, the body goes into the “fight or flight mode,” triggering the autonomic nervous system specifically activating the sympathetic nervous system and inhibiting the parasympathetic nervous system.
This action releases a hormone called epinephrine, which is often referred to as “adrenaline.” Additional stress may trigger other adrenal-related hormones. These hormones alter the stomach lining and food digestion take blood away from the digestive system and cause hyperventilation , dizziness, and more.
Stress can also cause muscle tension in your abdomen, and that added tension may squeeze your stomach in a way that leads to nausea. The gut also has an abundance of neurotransmitter receptors and is highly connected to the brain. It is possible that the way anxiety alters neurotransmitter levels in the brain may affect the gut as well.
Finally, during fight or flight, digestion is inhibited, which may affect how you process food and stomach acid and may lead to nausea.

What Happens Inside Your Body When Youre Nauseous

Not all the foods we eat are safe. Your body tries to fight against the intake of harmful substances by vomiting or making you feel nauseous. The vomiting process can be divided into two stages.
During the first stage you feel nausea and you might experience the occasional belch . Youll sometimes be able to avoid vomiting in this stage, especially when the cause of your nausea is known and is removed. Your stomach produces less gastric acid in this stage and your stomach functioning is slowed down by the vomiting centre in your brain. You produce more saliva and food is pushed back up from the duodenum.
Thats when the second stage starts: vomiting is now inevitable. Your abs muscles contract and at the same time your esophagus relaxes in a knee-jerk reaction. This causes your stomach content to move upwards.
You could try to suppress it, but the stomach content will find a way out through your mouth or through your fingers. You might start to sweat profusely and your heartrate will lower. If you throw up the cause when vomiting , you will feel a lot better afterwards. If theres a different cause to the vomiting, you will usually experience more bursts of nausea and vomiting.

Vomiting Illness And Anxiety
Vomiting is not a rare symptom of anxiety, but it’s not a common one either. Discussing your vomiting with a doctor is always a smart idea, especially if this is the first time you’ve vomited as a result of an anxiety attack.
But vomiting from anxiety can still be a very real problem.
Why Anxiety Causes Vomiting
The mind and the stomach are tightly linked. Studies have shown not only that the mind has an effect on the gut but that the gut can have an effect on the mind. The two may not be related in function, but the nerves and chemical receptors are connected.
When someone suffers from anxiety, it sends signals to the stomach related to the fight or flight response. Those signals alter the way that the stomach and gut process and digest food, causing nausea. In cases of extreme anxiety, this nausea becomes so strong that vomiting occurs.
Vomiting may be partly conscious as well. Because nausea makes a person feel as though they want to vomit, those that have greater control over their regurgitation response may encourage their body to vomit. It’s not “on purpose” in the sense that a person is trying to vomit, but with their mind they may force their bodies to let it out based on the way they’re concentrating on the sensation.
Heart Palpitations And Trouble Breathing
Stress can get your heart pounding, sometimes to the point where it becomes painful and legit scary.
Stress hormones like cortisol and adrenaline have a near-instant effect on your cardiovascular system. As a result, your heart rate spikes, your blood pressure goes up, and your breathing gets faster.
And it can sometimes lead to a vicious cycle. A rapid heartbeat and fast, shallow breathing can make you nervous or scared, which can cause your pulse and breathing rate to increase even more and actually make you feel breathless.

Youre Having Trouble Thinking Clearly
If youve been having a tough time concentrating on one task at a time, remembering things accurately, or just generally operating on a higher level, stress could be to blame. Stress makes it difficult for you to think clearly, as it clouds your thinking and makes it difficult to focus.
This mental fatigue sometimes happens when small stressors pile in at a volume with which we cant keep up. Things like making multiple tough decisions at work, handling ongoing interruptions, and juggling social commitments all of these can accumulate and start to weigh on you . If you don’t have a chance to hit the pause button and reset, brain fog could set in. Focus is a finite resource and when stretched thin, it falters.
The unfortunate reality of this mental fatigue is that it can affect your physical energy levels, too. If youve spent the whole day feeling exhausted just doing the tasks you that you normally knock out in one afternoon, your body will feel tired. For some, this perpetuates the stress cycle no energy for stress-busting outlets like meditation, creative endeavors, or exercise means nowhere to release that stress, and it remains a looming burden.
Can Anxiety Cause Shortness Of Breath
Certain anxiety disorders can cause feelings of shortness of breath.
General anxiety increases your respiration rate, causing you to breathe more rapidly than usual. This faster breathing, also called hyperventilation, isn’t the same as shortness of breath, however.
Shortness of breath feels like a tightening in your chest and often comes with trouble breathing. It’s not a common symptom of general anxiety.
However, similar to feelings of chest pain, shortness of breath is associated with panic attacks and panic disorder, a specific type of anxiety disorder.
Since it can be a sign of heart attack or another life-threatening condition, unexplained shortness of breath is a medical emergency. Whether you have a history of panic attacks or not, you should go to the emergency room if you’re experiencing sudden and/or severe shortness of breath.

Youve Been Extra Stressed
Ever had a nervous stomach or butterflies in your stomach? Then you already know that there is a strong connection between the brain and gut. In fact, the gut is often referred to as your bodys second brain. This is because the gut is partially controlled by the central nervous system and also has its own nervous system, known as the enteric nervous system. The systems are in constant communication, so when stress triggers a fight-or-flight response in the central nervous system, it also affects the gastrointestinal systems. As a result, stress can cause a host of digestive issues ranging from indigestion and constipation to diarrhea, and yes, nausea.

Can Anxiety Cause Nausea
Many different things can lead to nausea. We dont know exactly why this happens, but it appears to be a bodily response to something that irritates or disrupts the natural state. Did you eat too much? Nausea. Did you get an illness? Nausea. Have you spun around in a circle? Nausea. You didnt get enough sleep? Nausea. Did you run too fast? Nausea. Certain illnesses are associated with nausea, and it also often accompanies feelings of disgust.
The evolutionary purpose of nausea is thought to be to notify a person of something and prevent the person from repeating whatever they just did. Although unexplained nausea is possible, nausea is generally your bodys way of telling you that it doesnt like something that occurred or the results of that action.
Nausea is triggered by internal signals. These signals can come from all over the body from the cerebral cortex to the chemoreceptor trigger zone to the peripheral and vestibular systems. The messages travel toward the brain stem, where they trigger a series of actions that ultimately lead to feelings of nausea and the movement of the contents of the stomach up the digestive tract.
It should come as little surprise that anxiety can also cause nausea. Its intensity is largely related to the causes and types of anxiety youre experiencing. Not everyone will experience nausea, but those who do may have mild to severe nausea.
Nausea is one of the most common anxiety symptoms. But why does it happen, and what can you do about it?
