I would recommend that you have your Vitamin B12 levels checked. I was constantly losing weight & lost 45 lbs, had no energy, fatigue, had neurological symptoms & gastrointestinal issues & I developed a bopping up & down type of walking. I was seeing many specialists and a neuromuscular doctor finally diagnosed my deficiency. I had no B12 left in my body. He prescribed 1000 mco of B12 each day and within 6 weeks some of my symptoms started to lessen or abate. I still have many other health concerns but I highly recommend that you give it a try as it can’t hurt to take it.
