Understanding a Low Platelet Count: Key Insights
At 18 years old, I have generally been in excellent health, with the sole exception being eczema that I’ve dealt with since childhood. Today, I underwent a comprehensive blood test, and the results showed my platelet count at 133, with an MCV of 95.7 and a PCT of 0.14. All my other readings, including hemoglobin, were within the normal range. Additionally, I had a CRP test which confirmed there were no signs of infection. As I'm currently on the second day of my period, which has been quite heavy, I’m curious if that might have an impact on my platelet levels. I don’t experience any concerning symptoms, such as unusual bleeding or bruising, so the results are puzzling. I also had my INR and APTT evaluated, and those results fell within the expected range as well.

It’s understandable to be concerned about your blood test results, especially as a generally healthy 18-year-old. A platelet count of 133, while slightly below the typical lower threshold (which is generally around 150), can be influenced by various factors, including your menstrual cycle and overall health.
Key Insights:
- Platelet counts can fluctuate due to many reasons, and menstruation can indeed lead to a lower count temporarily. Heavy menstrual bleeding often contributes to reduced platelet levels as your body loses blood.
- Your other blood parameters being normal, along with the absence of symptoms like unusual bleeding or bruising, is reassuring.
Explanation:
Platelets are essential for blood clotting, and a count of 133, while slightly low, isn’t generally concerning if you're otherwise healthy and asymptomatic. The heavy bleeding during your period might be the primary factor here, as blood loss can lead to a temporary drop in platelet counts. The MCV (Mean Corpuscular Volume) and PCT (Platelet Crit) appear normal, which suggests your overall blood health is good.
Next Steps:
-
Monitor Your Symptoms: Keep track of your menstrual flow and any unusual bleeding. Note how you feel over the next week—if you experience any new symptoms (like unusual bruising, fatigue, or prolonged bleeding), take note of those as well.
-
Hydration & Nutrition: Stay well-hydrated and maintain a balanced diet rich in vitamins and minerals, especially iron, to help with blood health. Foods like leafy greens, nuts, and whole grains can be beneficial.
-
Follow-Up Testing: Consider a follow-up blood test in a few weeks post-menstruation to see if your platelet count normalizes. Since you have no concerning symptoms, this may be sufficient.
-
Awareness of Trends: If this low count is persistent or if your symptoms change, it would be important to revisit this with a healthcare provider for further evaluation, which may include looking into other causes of thrombocytopenia (low platelet count).

Persistent Pus Despite Multiple Antibiotic Courses?
Age: 26, Female. I’m dealing with a pilonidal cyst that seems relentless in producing pus. My treatment began with Bactrim DS on December 3rd. After culturing the infection, the results on December 10th indicated the necessity for Augmentin, which I subsequently started. Throughout this entire period, pus has been continuously draining, even prior to beginning the Bactrim treatment. The cyst ruptured on November 30th, and I consulted a dermatologist on December 3rd, during which they performed a minor incision to clean the area. I’m quite concerned that, even after all this time, there’s still a significant amount of purulent discharge. The initial antibiotic course was only for 10 days, although I was given a 14-day regimen of Bactrim.
Elevated White Blood Cells, Neutrophils, and Low Iron Saturation: A Year of Symptoms
Hello everyone, I'm a 31-year-old woman, standing at 5'4" and weighing 148 pounds. I was diagnosed with celiac disease back in 2008, alongside dealing with asthma, over 75 allergies, eczema, oral herpes, bipolar disorder type 2, ADHD, PTSD, and generalized anxiety disorder. For the past year, I have been receiving allergy shots and have noticed some improvements. Additionally, I've been diagnosed with a 2.2mm Rathke's cleft cyst. I've also faced hyperprolactinemia for a number of years, but I'm unable to take medication for it due to the risk of triggering manic episodes. My medication regimen includes Vyvanse at 70mg, Wellbutrin at 150mg, Vraylar at 3mg, Clonidine at 0.4mg, Valacyclovir at 500mg, Zyrtec, Breo Ellipta, NuvaRing, and liquid iron (Floravital) twice daily. I also use Albuterol as needed, take Klonopin at 0.5mg as necessary, and have Zofran 8mg on hand for nausea. Over the past year, I've experienced numerous troubling symptoms, such as significant hair loss, easy bruising, an increase of 25 pounds, breathlessness, and muscle fatigue during exercise — a stark contrast to my previous ability to skate 14 miles effortlessly. I frequently feel nauseous, struggle with insomnia, and often wake up throughout the night. No matter how much I sleep, I always feel exhausted. My lymph nodes have been consistently swollen for years, which I attributed to allergies. I do experience depression, but it’s relatively mild for me. I’ve also undergone some surgical procedures including a right labral reconstruction in 2023 with allograft, a tonsillectomy in 2015, and a left salpingectomy due to an ectopic pregnancy in 2020. I dealt with a second ectopic pregnancy in 2021, which required treatment with methotrexate. As for my lab results, my thyroid panel, lipid levels, and liver function tests came back normal. However, there were abnormalities in my complete blood count (CBC) and iron levels, which were tested on December 10, 2025. An ANA test conducted last year was normal, and I have tested negative for COVID-19, flu, and EBV. On November 24, 2025, I received multiple vaccines including Tdap, MMR, varicella, and hepatitis B all at once. I'm concerned that these vaccinations might have contributed to my unexpectedly high white blood cell count. My frustrations with my healthcare providers have grown, as they don’t seem to take my concerns seriously, often attributing my symptoms to stress. I’m exhausted from dealing with these persistent health issues and perplexed by the recent surge in cold sores, which have increased dramatically this year — something I previously experienced only once annually. I began taking Valacyclovir in January 2025 to manage this recurrence. Despite visiting my primary care physician five times since August 2024, I still feel unheard and dismissed. Any advice or insights would be greatly appreciated. Thank you for taking the time to read my situation.
Young Adult Experiencing Persistent Knee Popping and Pain
A 20-year-old male, who is 6'1" tall and weighs 168 pounds, identifies as white and is a non-smoker with occasional alcohol consumption. He does not take any prescription medications and does not use recreational drugs. Today, during a warm-up session that included jump roping and jumping jacks, he noticed his right knee emitting popping sounds with every step he took. Although he is experiencing discomfort in his knee, which has been a recurring issue for the past two months, he is unsure if the sounds are the source of his pain or if they are simply coincidental. The onset of his knee discomfort traces back to over two months ago when he was lifting a pallet at work and felt a sudden sharp pain in his leg. This incident was accompanied by a brief episode of blurred vision. Initially, the pain was quite intense, but it gradually improved with the use of a compression brace; however, this brace has not alleviated the popping sensation. The popping noise has persisted since it began around 4 PM and continues as of 10 PM. He is considering seeking urgent care if the symptoms do not improve by the next morning.
Concerned About Possible Incontinence or Excessive Sweating
Greetings, I apologize for the length of this message. Recently, I visited a urologist due to noticing some blood at the end of my urination (I’m 25 and male). This issue has occurred before a few months back, with only a couple of drops present. The doctor conducted a urine analysis, which fortunately came back clear of blood and signs of a urinary tract infection. He has scheduled me for an ultrasound for further examination. Since that appointment, I've continued to observe slight traces of blood every couple of days. Lately, I've become increasingly anxious—more than I ever thought possible. What’s been particularly troubling is that around the time of my appointment, I began feeling as though my underwear was damp. I can’t determine if this is due to a minor leakage of urine or if it’s simply perspiration resulting from my heightened anxiety. I have experienced stress before, but this sensation feels new to me. I am uncertain if it’s linked to the overwhelming stress I’ve been under or if there might be another cause. Apologies for going on at length. I’m really worried about the possibility of kidney issues or cancer, and I feel exhausted.
22-Year-Old Female Experiencing Abnormal Plasma Donation Results
Greetings, I'm a 22-year-old female and I consider myself relatively fit. I lead an active lifestyle, maintain a healthy diet, and have no known medical conditions. I've been donating plasma regularly for about four to five months without any complications. During my latest visit, the staff performed a standard blood test to analyze my serum protein electrophoresis (SPE). Today, the nurse informed me that my alpha-1 protein level returned higher than usual, reporting a value of 6.3, which exceeds the maximum reference level of 6. I’m somewhat confused by the measurement units used, as a quick online search suggests that this is not typical for alpha-1 levels. Additionally, I’ve discovered that taking oral contraceptives can lead to elevations in this protein. I've been on these medications for several months, even prior to starting my plasma donations; could this be the reason for my elevated level? Furthermore, I read that muscle inflammation might contribute to higher alpha-1 levels. I've been quite dedicated to my gym routine lately, so could that be a factor? I'm finding myself feeling anxious about this situation, particularly since I've learned that elevated levels could potentially indicate more severe health issues, such as liver or kidney complications, or even cancer. The nurse mentioned that I’m unable to have a follow-up test until the 19th of this month. Would it be advisable to consult with my regular doctor in the meantime to gain some clarity on this matter?
