Apparently it's the fructose in onions that causes stomach gas. Try cooking onions in a little oil until they're soft before adding them to foods - that will partially break down the sugar. Or steam them first. Also, reduce the amount you eat. A little onion goes a long way in my experience. You can also try cooking onions with stomach gas-alleviating spices like ginger, cumin, cardamom, caraway, turmeric, fennel, asefoetida (hing). Asefoetida is extremely strong, just use a small pinch, and heat it first in oil to reduce bitterness. It also can be an onion substitute for people who can't do onions (like me). The Japanese sea vegetable kombu is also recommended for stomach gas - if you can figure out what to do with it.
Most pediatric patients with hydrocephalus are treated with ventriculoperitoneal (VP) shunt placement. However, shunt malfunction is common and is usually caused by mechanical failure. Shunt obstructions may be confirmed with radioisotope examination or with fluoroscopically guided injection of iodinated contrast material into the shunt reservoir.
