Dear user I have gone throught your question I can understand you concern Did you feel trembeling in your hand or hool body? May I know please if you are diabetic?Did you had gastric bypass surgery?Did you have problems wuth small intestinum? More commonly trembling in this case is know like reactive hypoglycemia , you have postprandial hypoglycemia . I thought that you have postprandial hypoglycemia: If your blood glucose level that falls below 70mg/dl will verify this diagnosis . At the same time did you feel :Sweating, dizziness, confusion, or weakness or difficulty ith speech? Other causes is Low adrenals. My advised is to consoult with your physician. Test bloodglucose atthat monet that you feel trembeling. Take a saliva hormone test to check Cortisol levels ( may be your case we have lo adrenalin level) Check please if you have anemia? Allso I suggest you to balance your meals and snacks to include carbohydrates, proteins and fat. Protein and fat slow carbohydrate digestion . which helps avoid axtreme fluctuations in your blood suger levels. If you have worse symptoms in morning , consider changing your breakfast to include whole grain cereal , such as oatmeal with fresh fruit and walnuts . My advised is to consoul your physician , your local endocrinology . To chek your blood glucose at the time that you feel trembeling. To consoult for other cause like (gluten intolerance, mercury deficience, hyperthyroid etc)(but not in these case ) Hope this information is helpful. If you have other questions,feel free and ask. Best regards.
