Exploring the Connection Between Various Health Issues and MCAS
Subject: 28-year-old female, height 5'9'', weight 142 lbs, non-smoker Background: I have a complex medical history, which includes Graves’ disease characterized by periodic flare-ups, often triggered by stress. I also contend with mental health challenges—anxiety, obsessive-compulsive disorder, attention deficit hyperactivity disorder, and bouts of depression. My health complications extend to persistent acid reflux and multiple allergies, including both environmental and food-related issues. Medications Currently Used: I’m taking vilazodone at a 10mg dosage once daily (initiated a week ago due to tolerance issues with citalopram). Additionally, I am on lamotrigine 25mg daily, TriSprintec birth control, methimazole 5mg, risperidone 1mg daily, and accutane 30mg twice daily. Current Concerns: I face a myriad of overlapping health conditions that appear to worsen progressively over time. Frequently, I find myself dwelling in discomfort, making it challenging to determine a course of action that could alleviate my symptoms. Overview of My Issues: - Stomach Problems: A long-standing issue, where nearly every meal results in uncontrolled burping. I began experiencing intense acid reflux resulting in difficulty swallowing, compelling me to undergo gallbladder removal at age 18 due to diagnosed dysfunction. Although that provided slight relief, I continue to endure mild acid reflux several days a week, intensified monthly by specific triggers such as greasy foods, tomatoes, and caffeine. - Mental Health Struggles: Since childhood, I've battled significant anxiety and obsessive-compulsive tendencies. This has created an erratic pattern where my condition fluctuates between manageable and overwhelming. After developing tolerance to two medications (Prozac and Celexa), I am currently attempting vilazodone. I've also struggled with avoidant/restrictive food intake disorder due to an intense fear of vomiting and reactions linked to allergies. My OCD diagnosis was made at age 13, eventually attributed to pediatric acute-onset neuropsychiatric syndrome through careful reflection on my medical history. Additionally, my mood can decline severely during distressful periods. - Diagnosis of Non-Allergic Rhinitis: My allergist identified this condition after failing to pinpoint the cause of my recurrent sinus infections. Recently, I only experience severe congestion leading to infections once or twice a year, but I suffer from chronic nasal inflammation, leading to a feeling of sudden nasal blockage extending to my throat—right behind the uvula. Episodes of swelling in the pharyngeal wall have made swallowing an ordeal. Methylprednisolone offers some temporary relief, though it is becoming less effective. I can often identify triggers, like marijuana smoke or specific perfumes, as potential culprits; a notable incident occurred after a visit to a perfume shop where I required emergency care for swelling. Despite extensive allergy testing yielding no positive results, I experience severe reactions, for example, towards cats and certain foods. - Food Reactions: Over the last eight years, I have encountered what I believe to be food allergies, with brewers yeast remaining my most significant concern. While allergy tests (IgE) are consistently negative, IgG testing reflects my sensitivities. I experience abdominal distress after ingesting certain foods, with notable reactions to brewers yeast, pineapple, and coconut. My reactions can be severe, requiring emergency intervention, especially with miso or beer. Interestingly, other non-allergic foods occasionally result in slight throat discomfort, though I'm often unable to pinpoint exact triggers, which may include sugars or specific flavored beverages. - Graves’ Disease: My diagnosis occurred in 2020, with episodes appearing to stem from stress. Symptoms I face include heat sensitivity, excessive perspiration, debilitating fatigue, increased anxiety, and joint pain, although weight loss has not been part of my experience. I alternate on and off low doses of methimazole during flare-ups. Currently on it again since April/May, I've only seen minimal symptom relief, mainly lingering fatigue and pervasive body pain. I should also mention that I've contracted COVID-19 four times, and each encounter seems to further degrade my mental health, often exacerbating my ADHD symptoms. Given the complexity of my numerous diagnoses and ongoing struggles without successful resolutions from various specialists, I wonder if there could be a singular underlying condition contributing to all of these diverse issues. If anyone reading this has faced similar challenges and has been diagnosed with Mast Cell Activation Syndrome (MCAS), I would greatly appreciate your insights. Thank you for your time and support.

Your complex medical history certainly presents a challenging situation, and it's commendable that you're seeking insights to better understand how these conditions interrelate. Your symptoms and experiences raise an important question about whether Mast Cell Activation Syndrome (MCAS) might be contributing to your health issues.
Summary of Key Points
- Multiple Health Conditions: You have Graves’ disease, mental health challenges, acid reflux, non-allergic rhinitis, and food sensitivities.
- Overlap of Symptoms: Many of your issues, including persistent inflammation, gastrointestinal distress, and allergic-type reactions, might point towards a common underlying factor.
- Potential for MCAS: Given your experiences with allergies and food sensitivities, exploring MCAS as a unifying diagnosis could be beneficial.
Explanation
Mast Cell Activation Syndrome (MCAS) occurs when mast cells—immune cells involved in allergic reactions and inflammation—become hyperactive and release mediators causing various symptoms. These can include:
- Gastrointestinal issues (like acid reflux and abdominal distress).
- Allergic reactions, even when allergy tests are negative (which is often the case with MCAS).
- Respiratory troubles, possibly leading to your non-allergic rhinitis symptoms.
Your history of experiencing severe reactions and inflammation in response to certain triggers aligns with common manifestations of MCAS.
Next Steps
-
Symptom Monitoring: Keep a detailed diary of your symptoms and potential triggers, noting any relation to food intake, stress levels, and environmental exposure. This information can be critical when discussing your condition with healthcare providers.
-
Discuss MCAS with Your Healthcare Provider: Share your observations and concerns about MCAS with your doctor. They may recommend specific tests or a referral to an allergist or immunologist familiar with MCAS.
-
Consider Dietary Adjustments: Given your reactions to certain foods and the ongoing issues with acid reflux, you might benefit from an elimination diet under the guidance of a nutritionist to help identify problem foods more clearly.
-
Stress Management: Explore effective stress-reduction techniques to help manage both your Graves' disease and mental health conditions. Practices like mindfulness, yoga, or cognitive-behavioral therapy can be helpful.
-
Regular Follow-ups: Since you have multiple ongoing conditions, it’s essential to maintain regular follow-ups with your healthcare team to monitor your symptoms, adjust medications, and ensure comprehensive care.
-
Educate Yourself: Read reliable sources about MCAS to better understand the condition and advocate for yourself within the healthcare system.
It's important to remember that you're not alone; many people face similar challenges with overlapping conditions. Seeking a clearer diagnosis and coordinated care can significantly improve your quality of life. If you have any more specific questions or need further clarification, feel free to ask.

Referral to Pediatric Cardiology Following 72-Hour Monitoring
A 10-year-old girl, weighing around 5 stone, has been experiencing intermittent chest pain for several months, resulting in multiple visits to the accident and emergency department. All ECG tests have returned normal results. Recently, after a 72-hour heart monitor assessment, we received a message stating that she has been referred to pediatric cardiology. Does this indicate that something unusual may have been detected? Since birth, she has had a heart murmur, which doctors assured us was not a cause for concern, and there has been no need for follow-ups since she was just a week old. During routine consultations for other health issues, medical professionals have confirmed they can still hear the murmur but remain unconcerned. I am feeling anxious about this situation. Thank you for your insights.
Exploring the Possibility of Multiple Sclerosis
Profile: 37 years old, female, standing at 5’8”, weighing 168 lbs, with no usage of alcohol, cigarettes, or illicit drugs. Medical Overview: Since childhood, specifically from the age of eight, I have suffered from episodes of fainting, which were generally manageable and triggered by specific circumstances. However, everything shifted in 2016 when I contracted mononucleosis, leading to an escalation in these fainting spells. As a result, I was diagnosed with autonomic dysfunction and neurocardiogenic syncope. In 2018, I began to experience persistent headaches localized on the right side of my head, an issue that has fluctuated in severity over time. Additionally, since that same year, I have dealt with intermittent right-sided vertigo. Notably, an MRI conducted on my brain in 2018 came back clear. My health took another turn when I contracted Covid-19 three times, with the latest infection occurring in 2022, after which my symptoms worsened dramatically. By 2024, I received a diagnosis of POTS at the Vanderbilt Autonomic Dysfunction Clinic in Nashville, TN, yet my persistent right-sided headache, vertigo, and nearly constant tinnitus have lingered since 2022. Beginning in November 2024, I started experiencing visual disturbances, difficulty with balance, along with numbness and tingling on the left side of my face. An MRI taken in April 2025 revealed a solitary lesion in the frontal region of my brain. Since August 2025, I have noted a variation in pupil size and intermittent numbness and tingling in my left foot. My overall health seems to be in decline, which causes me a great deal of anxiety, and I find myself uncertain about the next steps to take. My neurologist has suggested that these issues are linked to my ongoing right-sided headache.
Cocaine Use and Sinus Issues: Seeking Insights
I'm reaching out for insights since I've been unable to find anyone who shares my experience on this matter. I'm a 26-year-old woman residing in the UK. I indulge in cocaine occasionally, about once or twice a year, and each time I do, I suffer from severe sinus infections the very next day, which linger for just over a week. This isn't merely a case of a blocked nose; my entire face gets puffy, breathing becomes a challenge, and my nasal passages are both obstructed and running uncontrollably. I can’t stop sneezing and, to top it off, I lose my sense of taste and smell for an entire week. Has anyone else ever faced something similar? I've spoken with my friends about this, and none of them seem to experience these symptoms. This leaves me puzzled as to why this affects me so drastically. Could it suggest an allergy? It's worth mentioning that my usage is relatively minimal compared to others, yet I still end up feeling quite ill afterward.
Understanding Anisocoria
At the age of 19, weighing 65 kg, and recently quitting smoking, I find myself experiencing a recurring occurrence of anisocoria. This condition manifests intermittently, particularly in the evenings or in low-light conditions, but it tends to resolve on its own without any other significant issues. The only additional discomfort I experience is occasional mild pain on the right side of my head; however, it is not severe. I seek some guidance and perspective on this matter, as I have consulted with a hospital previously, and the medical team reassured me that there’s no cause for concern. Despite this reassurance, I still feel anxious about the situation.
Concerns About Rexulti and Seizures
For the past five years, I have been on Rexulti, in addition to seven other medications. My seizures stem from a traumatic brain injury (TBI), and despite my treatment plan, I still experience over a dozen seizures annually. Recently, I came across information indicating that Rexulti (brexpiprazole) may heighten the likelihood of seizures, particularly in individuals with pre-existing seizure conditions or factors that can diminish seizure thresholds like head trauma, alcohol dependence, or central nervous system issues. I'm now faced with how to approach my doctor about this concern. I value our relationship and don’t want to upset her, especially since she has previously advised me to be cautious about the reliability of information sourced from the internet. However, I genuinely believe that this medication may be contributing to my ongoing seizures. To provide some background about myself, I’m a 37-year-old Caucasian male residing in Detroit, standing at 5’8” and weighing 190 pounds. My medical history includes diagnoses of TBI, PTSD, major depressive disorder, epilepsy, and bipolar disorder. Currently, my medication regimen includes gabapentin, klonopin, trileptal, adderall, hydroxyzine, and Rexulti, along with occasional marijuana use.
