Americans had a lot of questions about blood pressure in 2019. They also wondered about the keto diet, hiccups and more.

These three topics were among the top 10 most-searched health-related questions, according to new data from Google. The list tabulated our trillions of collective searches between January and early December of 2019.

In 2018, the most-searched health-related questions typed into good were about amyotrophic lateral sclerosis (ALS), endometriosis, and how long does weed stay in your urine.

Here are the 10 top most-searched for this year:

1. How to lower blood pressure

More than 75 million people have high blood pressure but just more than half are managing it well, according to the US Centers for Disease Control and Prevention. So people are turning to Google to try to find answers about how a healthy, low sodium diet, exercise, and stress relief might help them get it under control. Controlling blood pressure means a reduced risk of a heart attack, stroke, and even dementia.

2. What is keto?

The ketogenic diet (keto for short) was the most-searched diet for the second year in a row. The high fat, high protein, low carb diet forces the body into a state known as ketosis, which forces the body to burn fat molecules. Health experts express concern for keto dieters for the diet’s lack of sustainability. It might be a good quick fix, but it’s just too hard for most people to give up bread, pasta, beans and fruit for good. Still, Americans are always looking for a new way to shed a few pounds.

3. how to Get rid of hiccups

It’s the age old question, we have yet to solve—how do you get rid of hiccups? Hiccups seem to start and stop with no obvious reason, though we do know they start when something irritates your diaphragm, such as eating or drinking too quickly or feeling nervous. Most cases seem to go away within a few minutes, but lingering hiccups cause people to turn to Google in search of a fast fix.
