Can Diarrhea Result From Fainting And Striking Your Head?

4.0 rating based on 68 ratings

Vasovagal syncope, also known as neurocardiogenic syncope, is a type of fainting that occurs in response to certain triggers, such as emotional stress, pain, standing for long periods, or the sight of blood. The body’s natural response is to slow the heart rate and dilate blood. Common symptoms after a mild traumatic brain injury include headache, confusion, and loss of memory, known as amnesia. GI dysfunction resulting from head injury can cause nausea, loss of appetite, diarrhea, constipation, vomiting, food sensitivities and allergies, bloating and gas, heartburn and acid reflux, vitamin deficiency, abnormal weight loss or weight gain, and mental health issues.

Head injuries can cause headaches, dizziness, trouble concentrating, and other symptoms that often improve within days to weeks. Sudden episodes of fainting can occur when turning the head to the side due to pressure on the carotid artery. Pain can stimulate the vagus nerve and is a common cause of fainting.

Concussions can result from falls, sports activities, vehicular accidents, assault, or other direct injuries to the skull. A big movement of the brain (called post-concussive syndrome) can cause gastrointestinal symptoms such as diarrhea, nausea, and vomiting. Concussion symptoms are usually temporary but can include a range of physical symptoms, such as headaches, nausea, dizziness, fatigue, visual problems, poor balance, and short-term nausea associated with acute concussion (mild TBI).

Why am I suddenly pooping diarrhea?

The most common cause of diarrhea is the stomach flu (viral gastroenteritis). This mild viral infection most often goes away on its own within a few days.

Eating or drinking food or water that contains certain types of bacteria or parasites can also lead to diarrhea. This problem may be called food poisoning.

Certain medicines may also cause diarrhea, including:

  • Some antibiotics
  • Chemotherapy drugs for cancer
  • Laxatives containing magnesium

What are bad signs after bumping your head?

  • Been knocked out but have now woken up
  • vomited (been sick) since the injury
  • a headache that does not go away with painkillers
  • a change in behaviour, like being more irritable or losing interest in things around you (especially in children under 5)
  • been crying more than usual (especially in babies and young children)
  • problems with memory
  • been drinking alcohol or taking drugs just before the injury
  • a blood clotting disorder (like haemophilia) or you take medicine to thin your blood
  • had brain surgery in the past

You or your child could have concussion. Symptoms usually start within 24 hours, but sometimes may not appear for up to 3 weeks.

You should also go to A&E if you think someone has been injured intentionally.

Can a fall cause diarrhea?

Common Causes of Stomach Pain and Issues. In some cases, the stress of an accident and surrounding events may be enough to cause gastrointestinal symptoms like diarrhea, nausea, or vomiting. This may occur quickly after the events or in the following time as you recover. If this passes quickly, it is likely related to stress and should simply be monitored. However, other symptoms persist and should be evaluated by a car accident doctor in College Park.

While these symptoms can indicate a wide range of injuries, there are common causes that a doctor will look for first. Many of them are considered a part of Seat Belt Syndrome.

Seatbelts are typically made of two parts- the upper strap that is diagonal across your torso and a lower strap that is across your lap like a belt. Both parts are crucial in saving lives, but they may cause some damage of their own upon impact. When you are thrown forward by the impact of an accident, the lower strap can cause a “bruise” on the lap. This may actually be multiple bruises or welts along the waist, and may not appear immediately. The marks can range from mild to severe in looks and pain.

Is it normal to have diarrhea after an injury?

Is it normal to have diarrhea after an injury?

You might experience symptoms days or weeks after an accident has occurred. This includes stomach pain, diarrhea, and other gastrointestinal tract issues.

Abdominal pain and injuries can be severe, even life-threatening. You should visit your doctor or a specialist to screen for internal bleeding and organ damage. Even if you think your pain is slight or manageable, it could indicate a serious problem that needs to be treated immediately.

Talk to our Georgia car accident lawyers if you were internally injured in a car accident and need help with your personal injury claim.

Delayed Symptoms of Stomach Injuries. In the moment of the accident, the body releases endorphins and adrenaline to dull pain and help you stay alert. Even after these hormones’ effects fade, the body may go into a state of medical shock, masking deep injuries for a period of time.

Can a fall affect your bowels?

Etiology. Intestinal injury can result from either blunt or penetrating trauma. The majority of blunt abdominal trauma does not result in intestinal injury. Approximately three percent of blunt abdominal trauma results in intestinal injury, with the small bowel being the most common location. Penetrating traumatic injury is less frequent than blunt trauma; however, it more frequently results in intestinal injury. Penetrating trauma falls into two main categories: high-energy (projectiles) and low-energy (stabbings).

Epidemiology. Injury is one of the leading causes of death in people under the age of 44 years old. Like most traumatic injuries, the incidence is higher in males, with men accounting for approximately 80% of cases. Intestinal injury is the third most common injury associated with blunt abdominal trauma, following spleen and liver.

In penetrating injury, the small bowel is the most commonly injured, followed by the colon. In stab wounds, intestinal injury varies from 30% to 83%, depending on the patient’s body mass index (BMI). In patients with abdominal stab wounds, increased BMI is protective and is associated with a lower incidence of severe injury and need for operation.

How do I know if I’m ok after hitting my head?

Seek emergency care for an adult or child who experiences a head injury and any of these symptoms:

  • Repeated vomiting or nausea.
  • A loss of consciousness lasting longer than 30 seconds.
  • A headache that gets worse over time.
  • Fluid or blood draining from the nose or ears.
  • Vision or eye changes. For example, the black parts of the eye, known as the pupils, may be bigger than usual or unequal sizes.
  • Ringing in the ears that doesn’t go away.
  • Weakness in the arms or legs.
  • Changes in behavior.
  • Confusion or disorientation. For example, the person may not recognize people or places.
  • Slurred speech or other changes in speech.
  • Obvious changes to mental function.
  • Changes in physical coordination, such as stumbling or clumsiness.
  • Seizures or convulsions.
  • Dizziness that doesn’t go away or that goes away and comes back.
  • Symptoms that worsen over time.
  • Large head bumps or bruises, such as bruises around the eyes or behind the ears. It’s especially important to seek emergency care if these symptoms appear in infants under 12 months of age.

When symptoms occur in athletes. Never return to play or vigorous activity immediately following a concussion. Experts recommend that adult, child and adolescent athletes with concussions not return to play on the same day as the injury. Even if a concussion is suspected, experts recommend not returning to activities that can put the athlete at risk of another concussion. Gradual return to learning and physical activity is individual and depends on the symptoms. It should always be supervised by a healthcare professional.

Can head injury affect bowel movements?

The study focuses on gastrointestinal disorders in brain-injured patients, including feeding disorders, constipation, and fecal incontinence. Bowel dysfunction due to neurogenic bowel is a common complication, causing anxiety and limiting daily activities. However, the importance of gastrointestinal problems in brain-injured patients is often overlooked, and there are few reports on assessing bowel function and colon motility. Previous studies on constipation in brain-injured patients have mainly examined the frequency of defecation and subjective symptoms, without considering objective changes in colonic motility. To objectively assess colonic motility, colon transit time (CTT) is used, which has been reported in spinal cord injury patients, cerebral palsy patients, and acute stroke patients. The Rome II criteria for functional constipation recommends diagnosing constipation by assessing the hardness of stool, sensation of incomplete evacuation, and straining, in addition to the frequency of defecation. The study divided brain-injured patients into constipation and non-constipation groups using the Rome II criteria, comparing differences in constipation scores, Bristol stool form scale, and CTT between the two groups. The correlation between the site of brain injury, cognitive and physical functional ability, and CTT was also examined.

Can you have diarrhea after hitting your head?

Direct Cause #4: Stomach and Liver. Sometimes, patients experience changes to the digestion process as a result of significant ANS dysregulation. The part of the ANS responsible for the “rest and digest” process (the parasympathetic nervous system) can become depressed in relation to the “fight or flight” side (sympathetic). One effect of this, which is linked to PCS headaches, is increased blood in the head and, consequently, decreased blood in the stomach and liver.

As a result, your meals might not move through your GI tract at the right speed, resulting in symptoms like constipation or diarrhea. Filtering of the blood by the liver could also be affected, leading to less detoxification and decreased production of chemicals that help digest food. We also suspect that the influence of the ANS on the GI tract could result in new food sensitivities.

If you think you’ve developed a food sensitivity since your concussion, work with a nutritionist or another specialist to figure out which foods are causing your nausea and eliminate them from your diet.

  • I had a fall from a swing onto concrete. Rushed to hospital they treated my broken leg but never looked at other possible injuries. 6 months later I was having trouble walking, it looked like a line had been drawn down my body and my entire left side was paralysed. This has had a major impact on my life. If you have serious trauma insist on head scans and repeat if needed. If I had received treatment within weeks of injury I would not have a permanent disability now

  • Got into car accident not sure if I got a concussion but for two weeks felt sensitive,insomnia,dizzy. I felt better two weeks after just had the symptoms of insomnia, but 2 months in now and feeling still insomnia & some headaches but I’m thinking It can be due to stress because I’m unemployed so yea… not sure what you think I feel strong physically and got my balance.

  • Walked into a low hanging sign a few hours ago and am now feeling dizzy and tired. I have a history of concussion so I am worried. I feel a bit unbalanced but I have longstanding vestibular issues related to previous concussions. Worth pointing out that it’s hot outside and that I walked for quite a long time, which may also contribute to the fatigue or the dizziness. Should I worry?

  • Hit the top back of my head on the bunk bed frame when I was standing up 4 days ago. Didn’t have any of the said symptoms. I just kinda feel a little pressure on the area. A month prior to this, I also hit the back of my head on a barbell bar as I am about to lie down to exercise. Also didn’t feel any of the said concussion signs. Could the pressure that I’m feeling in my head right now a sign of concussion or just feeling the pain from hitting? Like some sort of soreness. Thanks!

  • Hit my head 5 days ago and was knocked unconscious for about 30-60 seconds. Didn’t experience symptoms until 48 hours after the accident, became very emotional, dizzy, loss of balance and eyesight got blurry at times. Symptoms are still there but not had bad as yesterday, would you say this is a standard concussion?

  • Hey! So last tuesday i whipped my beck around because i heard a sound. I hut my head on my car door at the end of my rotation. I blinked, didnt pass oht, head hurt immediately but i drove home fine. Head hurt where i hit it but on friday i walked seven miles just fine. Then on sunday i coukdnt open my jaw to eat, felt so tired, and crying from the pain and fear of a concussion. Do you yink whiplash, neck strain or concussion?

  • Okay so I got pulled by the hair off the ground, and slammed into the floor. The back of my head on the right side by the ear hit the ground. I just felt gushing in the head, room spinning, pain when I touch it, and a tingling sensation that lasted only for a little! When I walked it’s like I wanted to fall down. And also felt nauseous I did vomit hours later though. Next day my body is sore, headache, swollen kneck on the left side, and can barely hear in the right ear. Kind of hard to chew. Tired. What do you think? Is it permanent or not. Doctor said it’s a concussion, that it looks normal but I don’t feel like myself. Which makes sense

  • Hey i got hit by a metal rod at the back of my head when i fell down the stairs and i blacked out immediately was not able to talk after that it’s been yesterday today i can talk but i am not able to walk properly having an imbalance. My head seems ok to see there are no black and blue spots… Nothing is there but it pains like hell. What should i do??

  • (F 25) it has been 6 hours since a wooden door fell on the left side of my head, i just feel slight light headedness/ a little sleepy and sometimes superficial pain because of the bump, should i still be worried ? Thank you so much ❤️ Edit : i’ve been having anxiety all day now i feel nausea i Don’t know if it’s from the anxiety or the injury help
