As a registered dietitian nutritionist (RDN), I was surprised to find out that I had a thiamine deficiency in December 2015. My diet wasn’t perfect, but it was close. I never imagined I’d spend so much time trying to treat my own deficiency, but it’s been over a year the first lab work showed the deficiency and I’m still struggling with it. I’ve been asked to share my symptoms and experiences, so I’ll start back around the initial diagnosis.
Let me preface my story by sharing some information about myself. I’m a 46 year old female and I’ve always considered myself fairly healthy. I’m active, and I complete a minimum of 12,000 steps/day and often much more. That includes some form of aerobic activity daily. I’ve dealt with some annoying health problems, but nothing I considered major. I’ve had issues with insomnia, depression, nerve problems, migraines, hypoglycemia and GI distress (mostly diarrhea) for years or decades. I’ve also had some discomfort on the left side of my chest, on and off, which goes unexplained. I’ve seen many different types of doctors, including cardiologists, neurologists, gastroenterologists, psychiatrists, sleep specialists, endocrinologists, allergists, etc. Also, I have very early visual symptoms of glaucoma, but my doctor said there aren’t any signs of disease in my eye. No familial history of glaucoma, and I’ve never been diagnosed with diabetes. Separately, all of these symptoms seemed minor. Only within the last few years or so, did I begin to wonder if there was some sort of connection.
In the fall of 2014, I started a post-bachelors program in dietetics. I had returned to school almost two decades after completing my bachelors, and the road to this program was a long one. My insomnia seemed to be severe the night before exams. Sleep eluded me, even with the prescription sleeping pills. Anxiety, right? It never occurred to me that it was something else. After all, I’ve had insomnia issues for at least a decade. Sometime during the semester, I had seen a neurologist for some nerve testing. I had numbness and tingling in my feet, hands and arms. It would wake me up at night. I began seeing a doctor of osteopathy for manipulations to help with the nerve problems, too. Also, I had noticed some garbled speech and numbness in my tongue, but thought I was imagining it.
During finals week in December, my insomnia became severe. My physician prescribed Xanax, but I hated the way it made me feel. I felt my anxiety actually increased. Even after finals were over, sleep eluded me. I was piecing 3-5 hours of sleep together, if that. I had trouble eating a full meal and was losing weight. In addition, I was having discomfort on the left side of my chest, something that I had experienced in the past but was yet unexplained. All of this was attributed to anxiety. By the end of December, my physician prescribed a daily anti-anxiety medication. This medication made me nauseous and I had diarrhea. Of course, these symptoms didn’t help the weight loss. At no time did my physician do any lab work while this was happening. I was so miserable that I emailed my advisor to inquire about dropping out of the dietetics program. Fortunately, she wouldn’t entertain the idea and encouraged me to continue, noting that I could take an Incomplete if necessary.
By February of 2015, I was down to 103 pounds, (I’m 5’ 4” and 130 pounds currently). I was dragging myself to school. I had lost a lot of muscle mass, and couldn’t sit for long in class because of the lack of muscle. My face looked quite thin and my temples were hollowed out. In March 2015, I was weaned off the medications and began taking 7.5 mg Remeron, and Ambien as needed. The Remeron helped my appetite and I began regaining weight and strength. With the support of my professors, I was able to complete the semester, and even maintained a high grade point average!
Early in the fall semester, I listened to a lecture by an RDN who is an integrative and functional medicine certified practitioner (IFMCP). Based on her lecture, I knew my instincts about an underlying connection to all of my symptoms was correct. In November 2015, I had an appointment with that RDN. She recommended some blood work, which my primary care physician (PCP) reluctantly agreed to do. It was a lot of blood work, and fortunately my insurance covered it. There were many positive or problematic results, but among them was low thiamine (whole blood) at 29ug/L, a positive ANA test, TPO 693, as well as magnesium and ferritin were in the low normal range. After further autoimmune testing, it was determined that I have Hashimoto’s disease, too.
The low thiamine level could explain many of my symptoms, including, insomnia, nerve issues, migraines, precordial pain, weight loss and problems processing carbohydrate. The question is why was my thiamine level low? I had always thought my diet was relatively healthful. For years, I watched my added sugar intake because of trouble with hypoglycemia. My fiber, protein and water intake seemed adequate. I’m very careful with my fat intake because I had a cholecystectomy in 2009 and still have problems with lipid digestion. I rarely drank alcohol because of the hypoglycemia and insomnia. The only other beverage I consumed was tea, usually 1-3 cups per day. Furthermore, because of my hypoglycemia, I ate mostly whole grains and very little gluten, if any.
In January 2016, I began taking a B vitamin complex, magnesium, lipothiamine and some other supplements, including Ortho-Digestzyme to aid in lipid digestion. I made changes to my diet, including dairy free and gluten free. I began seeing some health improvements. Eventually, I added yogurt and cheese back into my diet, but remained gluten free. I was having fewer migraines and began sleeping without Ambien. That spring I was taken off the lipothiamine, but continued the B vitamin complex and magnesium. I graduated from the dietetics program in May 2016, something I feared wouldn’t happen only one year earlier.
At the end of October 2016, I had an infection (perhaps, due to an insect bite) on my outer ear which wouldn’t go away. My PCP prescribed a cephalosporin antibiotic for 10 days. Towards the end of November and into December, I was having increased nerve issues, occasional insomnia, mild apathy and anxiety, which was strange given I had nothing to be anxious about. Also, I had the same chest discomfort again. My thiamine level was tested and it was low at 32 ug/L. I was taking the B vitamin complex and magnesium all along, so my PCP was unsure what to do. I’ve since learned that some antibiotics, like the one I took, can deplete thiamine. I saw the RDN again and began taking lipothiamine again on 12/23/2016. I was taking 50 mg, twice a do with magnesium, in addition to the B vitamin complex.
My PCP planned to retest in a month to see if it was working. However, on January 20, 2017, I had an emergency appendectomy. During the surgery, I was given a cephalosporin antibiotic, but it was only during the surgery, not afterwards. It should be noted that I only missed one day of supplements because of the surgery. By the end of the first week, I strongly suspected my thiamine level had bottomed out, because my symptoms of anxiety, insomnia, nerve pain, etc., reminded me of what happened two years earlier. During that week, I was taking 50 mg lipothiamine twice a day, 200 mg magnesium and a potent multivitamin. Personally, I think the antibiotic, surgical procedure and recovery, and resulting diarrhea contributed to the low thiamine despite supplementation. I almost went to the ER in hopes that they’d give me a thiamine injection or IV, but decided to wait until Monday to see my PCP. Her suggestion was that I continue my supplements, then we’d retest in a month. One month later, my thiamine level was low still at 32 ug/L. My PCP said she isn’t comfortable giving intramuscular thiamine injections and suggested I see a gastroenterologist. I mentioned information I found on Hormones Matter, but I don’t believe my PCP was interested in reading the material. I feel like I’m being bounced around from one doctor to another. I’m going to see the gastroenterologist, whom I’ve seen before but I’m not hopeful that she’ll be able to help. I saw a neurologist recently, who was very kind and listened intently, but could only suggest an MRI and a DO, who “might” be able to help me, but that DO’s office is 1.5 hours away. Next week, I’ll go back to the cardiologist for a check-up because of the ongoing discomfort on the left side of my chest.
For now, I’m sleeping at least 6 hours a night, which feels like a lot to someone who’s experienced severe insomnia. My hypoglycemia is under control. I’m not sure if that’s because of the thiamine supplementation, the gluten free diet or both. The last time I had gluten, I experienced both mild insomnia and hypoglycemia, but again, my thiamine was likely low too. I feel I still have occasional memory issues, but maybe that’s age related. Also, the numbness and tingling in my extremities continues. Migraines occur much less and are less severe, usually. The mild vision problems linger, as well.
The RDN I’m seeing is uncomfortable with me taking more than 100 mg lipothiamine per day. At this time, she is recommending supplements to treat continued GI inflammation too. Here is my current regimen: 100 mg lipothiamine/day, 200 mg magnesium/day, multivitamin 1/day (RDN wants me to take 2/day), 28 mg iron w/vitamin C, sodium butyrate 600mg 4/day, NAC 600mg 2/day, Ortho-Digestzyme 2 capsules before each meal to help with lipid absorption, and about 4000 IU vit D3.
Unfortunately, I feel I’m just one missed dose of my supplements away from problems all the time now. I’m not sure how to find a physician who can help me solve this ongoing thiamine problem and don’t know where to turn next. Again, I’m going to see a gastroenterologist and cardiologist this month, but feel it may be more of the same. My father died at 45 years old of cardiovascular disease. I know thiamine deficiency can lead to cardiovascular problems too, which is why I’m going back to the cardiologist.
