Hydrocephalus Awareness Month Post 4: What does a shunt feel like?

The other day I read a post in one of my hydrocephalus Facebook groups that made me sad and also made me wonder. It was posted, "Does anyone wonder what it's like to not have a device in your head and tubing running down your neck and into your abdomen?" It made me sad because it makes me wonder if Nicholas will feel that way one day (maybe a cure will come in his lifetime!), but it also made me wonder what it actually feels like to have a shunt.

Obviously I can't ask Nicholas yet what it feels like to live with a shunt on a daily basis so I turned to the hydrocephalus community to ask them what it's like to have a shunt. I have a small community of people I know in real life with shunts but am a member of several hydrocephalus groups on Facebook and on Babycenter and they provided me with some insight.

The first thing I was told was that the side effects of having a shunt were far preferable to living with the pressure in your head from having untreated hydrocephalus. That having excess CSF was painful, caused nausea and also made you dizzy. That you experienced things like double vision and just overall felt terrible. Obviously left untreated, hydrocephalus can also lead to brain damage and death, so having a shunt is preferable to that.

Also, I heard very different things from people I asked. Some experienced nothing out of the ordinary that they were aware of and some experienced all of these things - so like hydrocephalus itself, having a shunt feels different for each individual person who has one.

The main things I heard were being able to "hear" the shunt. When a shunt turns on, most people say that they are aware. They can hear it buzzing, clicking, popping, or gurgling inside their heads. This depends on the placement of the shunt (the closer it is to the ear canal the easier it is to hear) and it appears to also depend on the type of shunt (programmable, non-programmable, maker, etc.). Shunts are not always on, they turn on when the pressure in the head indicates they should be. The newer
programmable shunts detect the level of pressure in the head and turn on when the pressure exceeds what the shunt has been programmed to maintain. Older, non-programmable shunts, were on levels of high, medium, or low pressure and would detect when the brain reached the threshold that each shunt was set for. The bad news with non-programmable shunts is that if the shunt is over or under draining, the shunt must be replaced with surgery. Nicholas has a programmable shunt which means if we determine (and we have, several times) that his shunt is under draining, it's an office visit and a strong magnet is used to reset the shunt to a better level.

Another complaint is that when the shunt is draining, if the tubing is placed close enough to the ear, it can mess with a person's equilibrium. Because there is fluid running through a tube near the eustachian tube it can make people feel dizzy. This doesn't appear to be a common side effect, but has been mentioned in the community.

Most neurosurgeons leave a large amount of tubing curled up in the abdomen when treating children (Nicholas's did for this exact reason) so that as the child grows, the tubing can stretch and revisions (more brain surgery) are not necessary as long as the shunt continues to function properly. I have been told that as the child grows, it is typical to feel some tightening or tugging as the shunt tubing breaks loose of adhesions under the skin that were formerly created and lengthen under the skin. I imagine that must be fairly uncomfortable.

Weather is a big one. Most surgeons will tell you that weather has very little to do with the pressure inside the head, but almost every single person I've talked to who has hydrocephalus and is treated with a shunt has said that when the weather changes, they get headaches. It's apparently a big debate within the hydrocephalus community. We have seen it first hand with Nicholas. If a big storm is rolling in, he becomes very uncomfortable and cries. If we give him Tylenol, it seems to relieve and relax him. I've been told by my co-worker with hydro that if it's very hot, she gets headaches. She has found that wearing hats helps to reduce the headaches.


Abdominal discomfort is another common complaint. It seems that the CSF draining into the abdominal cavity creates acid reflux in a significant number of hydrocephalus patients.

While not every person who has a shunt experiences all of these, these complaints come up time and again. And again, every person I talked to said that this is clearly preferable to living with hydrocephalus untreated and obviously better than facing death so they take their side effects with a grain of salt, some ibuprofen, and maybe some Tums.
