People hunting for a new primary care provider may have a hard time finding a doctor who's taking new patients. But a number of primary care providers can do the job, including four types of physicians and two types of advanced practitioners.

There are many ways one can try to avoid constipation. For example, lifestyle remedies may help—such as increasing dietary fiber, getting regular exercise, and drinking three to six cups of water per day. If those approaches don't work, doctors recommend using fiber supplements, such as psyllium husk (Metamucil), methylcellulose (Citrucel), or wheat dextrin (Benefiber). Another supplement that might help is magnesium. When all strategies fail, it may be time to try over-the-counter medication. One option is an osmotic laxative such as polyethylene glycol (Miralax).
