Breath-Holding: Understanding the Risks to Brain Health
I’m curious about the limits of breath-holding and its impact on brain health. Specifically, how long can a typical person sustain a breath before facing the risk of irreversible brain injury? If someone loses consciousness due to breath-holding, does it inevitably lead to brain damage or is that merely a potential risk? Additionally, when you push yourself to hold your breath until discomfort sets in, should you be concerned about the onset of brain injury?

Breath-holding can be risky, particularly regarding brain health, and it’s great that you’re seeking to understand the limits and implications. Here is a breakdown of important points:
Main Points:
- Breath-Holding Limits: Most individuals can hold their breath for about 30 seconds to 2 minutes before experiencing significant discomfort.
- Risk of Brain Injury: Loss of consciousness from breath-holding can lead to impaired brain function, but not all instances result in irreversible damage.
- Discomfort as a Warning: Feeling discomfort is your body's way of signaling that you need to breathe; pushing through that can be risky.
Explanation:
- The brain is highly sensitive to oxygen deprivation. Generally, a lack of oxygen for more than 3-5 minutes can start leading to irreversible brain injury, although this varies by individual health and circumstances.
- If you hold your breath until you lose consciousness, you may experience a temporary loss of function, which can lead to potential brain injury, although many recover fully without lasting effects. The degree of risk depends on individual factors, such as overall health, length of unconsciousness, and previous neurological conditions.
- Discomfort while breath-holding indicates that your body needs oxygen. Continuing beyond this point increases the risk of passing out and can lead to increased risks of injury or changes in brain health.
Next Steps:
- Stop Breath-Holding Upon Discomfort: If you feel discomfort while holding your breath, it’s crucial to stop and breathe normally.
- Educate Yourself: Consider researching breath control safely, especially if you practice breath-holding intentionally, like in swimming or free diving.
- Monitor Your Body's Signals: Pay attention to how your body responds during breath-holding activities and avoid pushing limits that result in pain or significant discomfort.
- Consult a Professional if Needed: If you practice breath-holding techniques regularly or at lengths that cause concern, consider speaking to a healthcare professional to ensure you’re doing so safely.

Recurring Injury in the Shoulder and Rib Area
I’m a 34-year-old female, standing at 5'4" and weighing 165 pounds. My only prescriptions are for mental health issues, specifically bipolar disorder type 2 and complex post-traumatic stress disorder. Professionally, I work as a bartender and maintain a fairly active lifestyle. I don’t smoke, use marijuana very occasionally, and abstain from alcohol altogether. Back in February, I experienced a strain in my left chest wall. This occurred when my dog, who weighs 75 pounds, unexpectedly bolted on her leash, causing me to twist suddenly. I had her leash held tightly in one hand and was caught off guard by her quick movement. Then, in April, while joking around in my kitchen, I decided to leap into the air. Although I didn’t perceive a hard landing, I distinctly felt a pop in my ribs during the jump. After a visit to my doctor and an X-ray, I was diagnosed with costochondritis. They recommended treatment with lidocaine patches and naproxen to alleviate the discomfort. Recently, precisely one week ago, I fell from my paddle board while attempting to stand up, landing predominantly on my left side in the water. Since that incident, I have been experiencing persistent pain in my ribs, particularly on the left side, along with severe pain in the back of my shoulder. Engaging in activities like deep breathing, sniffling, blowing my nose, or coughing triggers extreme sharp pain. While I can raise my arm over my head without discomfort, most other motions exacerbate the pain, sometimes giving the sensation that something is lodged in that area. I am making efforts to schedule an appointment with my primary care physician as soon as possible, hoping to get more clarity on my condition. I find that urgent care may not be beneficial since they typically only perform X-rays and offer little additional help. To manage my symptoms, I’ve resorted to methods like KT tape, lidocaine patches again, and CBD balm. Additionally, I still have some naproxen left from my earlier prescription that I’ve begun to take again. Thank you for taking the time to read my situation; I hope I have shared sufficient information!
Drinking and Self-Harm: A Distressing Situation
I’m a 16-year-old female, and I recently consumed a lot of alcohol, leading to a situation where I engaged in self-harm. When I'm emotionally struggling, I often turn to drinking, and sadly, this time it escalated further. The last thing I clearly remember is feeling a strange taste in my mouth and experiencing some facial twitching before I lost consciousness and found myself on the ground. After that, I harmed myself quite severely, cutting deeply into my thigh. The bleeding initially was quite heavy, although it seems to be tapering off somewhat as I apply pressure. Unfortunately, my parents are away, and so are my friends. I’m debating whether I should drive myself to the emergency room or continue applying pressure and hope the bleeding stops on its own. I apologize for any mistakes in my writing.
Questions Regarding My Gastritis Diagnosis
Hello! I received a gastritis diagnosis on Friday after a rather unpleasant emergency room visit, and I have a couple of questions I'd like to ask. I'll share my experience leading up to this point, my symptoms, and then pose my concerns. About a week ago on Monday, I took ibuprofen for some back discomfort at bedtime. Over the years, I've frequently used ibuprofen for mild chronic pain, generally around 400 mg every other day, particularly since I also suffer from migraines and endometriosis, which intensify during my menstrual cycle. I am a 29-year-old woman, weighing 230 pounds, smoking a pack of cigarettes every day, and consuming six cans of dark soda daily. After taking the ibuprofen that night, I experienced a severe episode of pain that I now realize was related to gastritis. It felt as though my stomach's protective mucus layer was being destroyed, leading to vomiting due to the intense discomfort. Concerned by the appearance of my vomit, I went to the emergency room, where they performed several tests, including bloodwork and X-rays. The first physician I consulted suspected classic gastritis based on my symptoms and stated she would return after reviewing the X-rays. Upon her shift change, the next doctor assessed my condition and suggested there was a 90% chance it was gastritis, but raised the possibility of it being related to my gallbladder as well. They administered a dose of Mylanta, IV Zofran, and potentially Pepcid, which significantly alleviated my discomfort, though I was not entirely symptom-free. The doctor seemed to think my improvement indicated a gallbladder issue, so they proceeded with an ultrasound and later discharged me, noting the presence of gallstones. They scheduled a high-resolution ultrasound and an appointment with a surgeon for the following Friday. However, about an hour after leaving, my pain returned, despite eating a diet considered safe for gallbladder issues. The night before my surgery consult, I prepared a homemade chicken soup suitable for gallbladder patients, but afterward, my stomach reacted intensely—essentially like pouring salt onto a wound. During my visit, the surgeon explained that she believed my gallstones were asymptomatic and confirmed I was indeed experiencing gastritis. She elaborated on what this means and remarked that I fell within the typical profile for such a diagnosis. She prescribed a six-week regimen of Carafate, 40 mg Pepcid, and proton pump inhibitors, alongside instructions for an additional stomach shot. Once I got my prescription for Carafate, I took it alongside a peach smoothie, which was soothing to my stomach, providing immediate relief. At home, I followed the directions and took my other medications after waiting for an hour post-Carafate, leading to a feeling of overall improvement. However, I'm struggling with some issues I hope to address: How can I manage this persistent insomnia? I occasionally use Trazodone for severe nights, but I'm quite hesitant about taking any medication regularly. Additionally, I am experiencing constant hunger. I'm attempting to focus on easy-to-digest, protein-rich foods, yet my stomach still feels bloated, and I can only consume small portions before finding myself hungry again within two hours. Will this situation improve as the bloating subsides? I've taken a week off work for recovery, but my sleep has been severely disrupted since the day of my appointment—prior to that, I had trouble sleeping due to pain, and as soon as the pain lessened, I found myself feeling extremely fatigued. During my healing phase, should I expect to feel a high level of fatigue? With my menstrual period approaching, which typically brings additional discomfort, how should I cope with the pain considering my gastritis? Would it be safest to manage without medication? I apologize for the lengthy message and the multitude of questions, but I have many concerns regarding my situation. I appreciate your time and assistance!
