Former President George H. W. Bush remains in a Houston hospital, where he is being treated for chronic bronchitis.

The 92-year-old Bush Sr. checked into the hospital on April 14 with a mild case of pneumonia, reports the Daily Mail.

His spokesman, Jim McGrath, tweeted an update on his condition on April 25, quoting a statement by Dr. Clint Doerr, a pulmonologist at the hospital:

While President Bush has recovered from pneumonia, he continues to deal with the effects of chronic bronchitis, which is a condition more prevalent with age. This means his airway has a constant, low-level inflammation that can aggravate the symptoms of pneumonia. We continue to monitor his cough and breathing, and expect ot discharge him by the end of the week. Once President Bush is home, we will continue aggressive respiratory treatments to help minimize the effects of the chronic bronchitis.

According to the National Heart, Blood, and Lung Institute, there are various treatments for the disease, which are summarized for readers on the official website:

If you have chronic bronchitis and also have been diagnosed with COPD (chronic obstructive pulmonary disease), you may need medicines to open your airways and help clear away mucus. These medicines include bronchodilators (inhaled) and steroids (inhaled or pill form).

If you have chronic bronchitis, your doctor may prescribe oxygen therapy. This treatment can help you breathe easier, and it provides your body with needed oxygen.

One of the best ways to treat acute and chronic bronchitis is to remove the source of irritation and damage to your lungs. If you smoke, it's very important to quit.

Bush Sr.'s son, former President George W. Bush, visited his father in the hospital shortly after he was admitted. "Big morale boost from a high level delegation," Bush Sr. tweeted. "No father has ever been more blessed, or prouder."

It's the second time this year that the elder Bush has been hospitalized for pneumonia. In January, he and wife Barbara Bush had to skip President Donald Trump's inauguration while they were both recovering from the illness.

"Barbara and I are so sorry we can't be there for your inauguration on January 20th," Bush Sr. wrote in a note to Trump at the time. "My doctor says if I sit outside in January, it likely will put me six feet under. Same for Barbara. So I guess we're stuck in Texas. But we will be with you and the country in spirit. I want you to know that I wish you the very best as you begin this incredible journey of leading our great country. If I can ever be of help, please let me know."
