Viral social media posts reveal unsettling human body facts

Public debate continues over teeth and organ positioning

A viral post claiming that teeth are not bones has sparked negative reactions among social media users.

A user identified as @shellyybabyy shared information on threads.com regarding how organs return to their anatomical positions. Peristalsis moves food through the digestive tract but does not move organs back to their positions.

Homeostasis maintains the body without external assistance

The human body functions as a biological system that maintains itself within precise limits without any external assistance. This internal balance is called homeostasis.

The body regulates vital factors including blood pressure, body temperature, oxygen levels, and sugar content. Billions of neurons communicate through chemical and electrical signals to keep the body functioning.

The heart adjusts itself immediately during movement, exercise, or moments of fear. Constant changes, such as blood flow, hormone shifts, and ion exchanges between cells, protect internal stability.

Physiology maintains life through controlled movements rather than silence. Most bodily functions operate as a silent wonder, though people notice their physical state when they experience pain, shortness of breath, or fever.

Kyle S. shares experience with varicose vein removal

Kyle S. noticed enlarged varicose veins, end-of-day fatigue, and a restless feeling in his legs while training for a marathon. These veins are raised or bulging beneath the skin and develop when valves fail to move blood efficiently toward the heart, causing internal pressure to build.

He sought an evaluation for his condition at United Vein & Vascular Centers in Gilbert. He underwent radiofrequency ablation, VenaSeal, and Varithena treatments. Radiofrequency ablation uses thermal energy, VenaSeal uses a medical adhesive, and Varithena uses an injectable microfoam to close affected veins, which allows blood to reroute through healthier veins.

Following his treatment, Kyle S. said, "My legs feel lighter, I don’t experience any pain anymore, and the cosmetic portion of it is better".

Varicose veins cause chronic pain and discomfort

Varicose veins are enlarged and twisted superficial veins, typically found in the legs, that can cause fatigue, pain, itching, and nighttime leg cramps. These veins can lead to complications such as bleeding, skin ulcers, and superficial thrombophlebitis.

Varices in the scrotum are known as varicocele, while those around the anus are known as hemorrhoids. The physical, social, and psychological effects of varicose veins can lower a person's quality of life.

Dr. Lev Khitin leads New York vein treatment research

Dr. Lev Khitin founded the New York Vein Treatment Center in 2009, which treats vein disorders in Manhattan and Brooklyn. He and his clinical team evaluate and treat spider veins, varicose veins, and venous insufficiency. Khitin is a Fellow of the American College of Surgeons and the American College of Phlebology, and he holds board certifications in both general and thoracic surgery.

Khitin has over 20 years of experience and has performed more than 20,000 procedures. In 2009, he founded the New York Vein Treatment Center to provide in-office treatment for circulatory disease without the need for general anesthesia or a week of recovery. He holds a surgical device patent and was a principal investigator on national clinical trials for pharmaceutical companies.

Before his work in vein treatment, Khitin spent nearly 10 years operating on hearts and aortas in Charleston, Birmingham, and Chicago. He repaired aneurysms and published research on topics including Marfan syndrome and spinal cord protection during aortic surgery. He completed training in general surgery at Stanford and the University of California, San Francisco (UCSF), vascular surgery at the Lahey Clinic, and cardiothoracic surgery at the Medical University of South Carolina.

Khitin conducted research on molecular signals in blood vessels at UCSF, publishing in the Journal of Biological Chemistry and the Proceedings of the National Academy of Sciences. Separately, the Chicago Tribune reported that nearly 1,000 civilians in the United States were shot and killed by police officers in 2015.
