Could Progesterone Be the Cause of My Hair Loss?
Age: 33, Weight: 215 lbs, Height: 5'6" Medical Conditions: Diagnosed with Autism, ADHD, PMDD, Endometriosis, and PCOS. Underwent a right thyroid lobectomy due to a benign, large dominant nodule. Current Medications: Taking 200 mg of Progesterone for two weeks on and two weeks off to help regulate menstrual cycles, 36 mg of Concerta for ADHD, and 750 mg of Metformin for PCOS (non-diabetic). I began my progesterone treatment 12 days ago, and it has been quite beneficial. I feel less fatigued during the latter part of my menstrual cycle, which is a positive change. However, I've also experienced significant hair shedding lately. While my hair looks fine in appearance, it seems to be falling out more than usual. I notice strands everywhere, and it's something I've never encountered before. Is this a common side effect? Should I be concerned about going bald in the future? I am grateful for the positive effects of progesterone, yet I'm anxious about potentially losing my hair, especially since my hair is very fine and soft. I have edited this to include additional information I previously overlooked.

It's understandable to feel concerned about hair shedding, especially when you're experiencing positive effects from your progesterone treatment. Hair loss after starting new medications can occur, but it isn’t always related to the medication itself. Let’s break it down.
Main Points:
- Hair shedding can happen for various reasons, including hormonal changes, stress, or underlying health issues.
- Progesterone can influence hair growth, but it's not typically known to cause significant hair loss in most patients.
- Monitoring your situation and being aware of additional factors is crucial.
Explanation:
Progesterone contributes to the balance of hormones in your body, and while some individuals may experience changes in hair growth with hormonal therapies, significant hair loss is not a common documented side effect. However, your existing conditions like PCOS and the hormonal imbalances associated with it could lead to increased hair shedding. Stress, changes in routine, or other health changes can also contribute.
Given your experience of both positive effects and hair shedding, it's important to assess the situation closely.
Next Steps:
- Track your hair shedding: Keep a diary for the next few weeks, noting how much hair you're losing compared to normal, when it happens, and any other new symptoms you might observe.
- Focus on hair care: Use gentle, sulfate-free shampoos; avoid heat styling; and limit tight hairstyles that may stress your hair.
- Review your nutrition: Ensure you’re getting enough vitamins and minerals, especially those important for hair health (like Biotin, Vitamin D, Iron). Consider a balanced diet or possible supplements if necessary.
- Manage stress: Engage in relaxation techniques or mindfulness to help mitigate stress that might contribute to hair shedding.
- Consider timing: Sometimes hair shedding has a delayed onset based on hormonal changes. Monitor how your hair responds over the next menstrual cycle.
- If shedding persists or worsens over the next month, consider discussing options with your healthcare provider to explore possible adjustments or additional treatments.
It's great to hear that you're experiencing benefits from your progesterone treatment. Keeping track of your symptoms will be beneficial in making informed decisions about your care. You're not alone in experiencing these concerns, and many options exist to support both hormonal health and hair vitality.

Unusual Skin Rash
Hello! I'm a 17-year-old female and I just discovered an unusual rash covering my body upon waking up this morning.

I'm feeling quite anxious about this situation, so I would appreciate any insights into what it might be and the level of risk involved. Thank you!

Concerns About Skin Cancer Risk After Sunbed Use
Reflecting on my experiences in my early twenties, I (27F) frequently visited the tanning beds at my gym, often laying under those harsh lights daily, usually without applying any sunscreen, resulting in noticeable burns. This habit wasn’t long-term but rather occurred intermittently whenever I felt particularly pale. My last encounter with a tanning bed was in April of the previous year. Lately, I’ve been alarmed to see new moles appearing on my skin, as I can’t help but remember how I recklessly used tanning beds, even if my sessions spanned just a few days at a time over the past seven years. This has led me to question whether my decision to stop tanning has reduced my risk of skin cancer and melanoma, or if that risk remains significantly high despite my change in behavior.
Experiencing Skin Sensitivity After Starting Gabapentin
Greetings, I've recently begun taking Gabapentin, initially starting with one 300mg tablet daily for the first week, and I have since increased to two tablets each day, currently entering the second week of this dosage. Lately, I've noticed an increase in skin sensitivity, making any form of contact – whether from clothing or bedding – extremely uncomfortable. Although Gabapentin has significantly contributed to improvements in my anxiety, sleep quality, and cravings, this skin irritation is proving to be quite distressing. As a former moderate user of nicotine through vaping, I've found that even the smallest quantity of nicotine now amplifies the discomfort to unbearable levels. I'm attempting to reach my physician for guidance, yet I’m also looking for insights in the meantime. I believe (please correct me if I'm mistaken) that since I’m still relatively early in my Gabapentin treatment, stopping the medication might not pose a significant risk for withdrawal symptoms. Currently, I am abstaining from nicotine, but I’m finding myself experiencing some anxiety and irritability related to this abrupt cessation, despite the beneficial effects that Gabapentin usually has on nicotine withdrawal. This situation leaves me feeling conflicted. The irritation of my skin is severe enough that I'm committed to avoiding nicotine until further notice, yet quitting nicotine cold turkey is also quite challenging. I am contemplating whether to discontinue Gabapentin as well to evaluate what effects a break from both substances might have. I haven't observed any rashes or additional symptoms (I am informed about the severe rash and allergic reactions that Gabapentin can cause, and I believe I’m not experiencing those issues; I previously took Gabapentin and Pregabalin many years ago without any problems). Hence, I seek some advice regarding my situation: 1. Am I at a point in my Gabapentin treatment where I should be concerned about potential withdrawal effects? (I have no past history of seizure disorders.) 2. Does this type of skin hypersensitivity warrant an immediate discontinuation of the medication, a gradual tapering, or could it possibly subside given more time? 3. Does the fact that nicotine exacerbates this discomfort make sense? The correlation is striking since I feel an aversion to touch almost immediately after using a vape. (I'm aware of the dangers associated with nicotine and vaping; I am currently working on reducing this habit, but this is not the main focus of my inquiry.) Thank you for your time and assistance! 36-year-old male from Canada, with no other significant health issues.
