Hello! Welcome and thank you for asking on HCM! I understand your concern and would like to explain that there are different causes related to your symptomatology. You should know that dehydration, loss of the fat tissue when losing weight, malnutrition and skin thinning and some drugs (like steroids), can induce these changes. Some metabolic disorders (like thyroid and adrenal gland dysfunction) could also lead to these small vein changes in your body. From the other hand, straining physical exercise and prolonged standing up position can induce a vein insufficiency and small vein changes, mainly in your feet. But in that case these changes would be permanent. I recommend consulting with your GP for a careful physical examination and some blood lab tests : - complete blood count - thyroid hormone levels - cortisol plasma levels - kidney and liver function tests - blood electrolytes, etc. A Doppler ultrasound of the leg vessels would be necessary. Meanwhile I recommend you to take plenty of fluids (water and juices) and a balanced diet full of vitamins and proteins. Hope to have been helpful! Best regards, Dr. Iliri
