President Joe Biden announced on Sunday that he has withdrawn from the 2024 presidential race.
While the White House press office told Fox News Digital on Monday that “health was not a factor” in the president's decision to withdraw, several doctors expressed concern about signs of cognitive decline following Biden's widely criticized performance in the June 27 presidential debate.
Two medical experts told Fox News Digital that they believe Biden's decision to step down is in the best interest of The President's Health.

Biden, however, is not the only president whose reelection was potentially thwarted by health problems or concerns.
Here are five more.
1. Chester A. Arthur (21st President, 1881-1884)
After being elected the 21st president of the United States in 1881, Chester Arthur experienced health complications from malaria, which remained endemic in Washington, D.C., throughout the 19th century, according to the National Institutes of Health (NIH).
In 1882, Arthur continued to suffer from progressive fatigue, extreme weight loss, and peripheral edema, the NIH reported.

After a more detailed health check, Arthur was diagnosed with Bright's disease, now known as chronic kidney disease.
The president's health worsened during his final two years in office, with reported symptoms of fluid retention, chills (shaking or shaking), nausea, and crampy abdominal pain.
As the 1884 election approached, Arthur sought a second term, but lost the Republican nomination to James G. Blaine, then Speaker of the House of Representatives.
Blaine lost the election to Democrat Grover Cleveland.
Arthur died on November 18, 1886, at age 57, according to the Smithsonian.
2. Theodore Roosevelt (26th president, 1901-1908)
Theodore Roosevelt assumed the role of commander in chief at age nearly 43 in 1901, following the assassination of President William McKinley, according to the White House Historical Association.
Roosevelt was re-elected in 1904.

After William Howard Taft's term began in 1909, Roosevelt decided to re-enter the race in 1912, creating his own “Bull Moose” party.
While campaigning on October 14, 1912, in Milwaukee, Wisconsin, Roosevelt was shot during an assassination attempt outside the Gilpatrick Hotel.
The bullet was stopped by Roosevelt's heavy coat, his steel-reinforced eyeglass case and his 50-page speech folded in the inside right pocket of his jacket, as History.com reported.
The bullet pierced the president's right chest but did not damage his lungs. It lodged between his ribs, which was considered safer than surgery.

Roosevelt continued his campaign while he recovered, but was defeated by Democrat Woodrow Wilson in the 1912 election.
3. Woodrow Wilson (28th president, 1913-1920)
Woodrow Wilson served two full terms and intended to run for a third.
But the then-president was “severely affected” by a neurological condition that caused him to suffer strokes before and during his presidency, according to the NIH.

Before taking office, three strokes affected his right hand and left arm, causing blindness in his left eye.
A devastating stroke suffered during his presidency in October 1919 left Wilson paralyzed on his left side and with partial vision in his right eye.
He was confined to bed for several weeks, the NIH reported.
Wilson did not recover sufficiently from this episode.
In the 1920s, Republicans sought confirmation that he was still fit to perform his duties as required by the Constitution.
The president's physician, Dr. Cary Grayson, declined to comment publicly on Wilson's health as he seeks re-election to a third term.

However, when the Democratic Convention came around that summer, Grayson shared Wilson's poor health with party leaders and rejected the idea of a third term.
Ultimately, Wilson did not win the presidential nomination and Republican Warren G. Harding was elected in 1921.
4. Franklin Delano Roosevelt (32nd president, 1932-1945)
Franklin Delano Roosevelt (FDR) was the only American president to serve more than two terms, having been elected to four terms during World War II.
Roosevelt had suffered from health problems since his paralysis as a result of polio at age 39, according to the Franklin D. Roosevelt Library and Museum.
During his third term, Roosevelt was diagnosed with a heart condition, which was kept hidden from the public before his re-election to a fourth term, the NIH reported.
Throughout 1944, Roosevelt's team of doctors monitored his deteriorating health, continually recording high blood pressure measurements.

These heart complications were attributed to the “endless stress and strain of war,” according to the FDR Library and Museum.
Roosevelt was elected as the Democratic nominee in 1944 and continued his campaign, even while facing skepticism about his physical fitness for office.
Although he won his fourth presidential election, Roosevelt was “weakened” by his condition, according to the NIH.
On April 12, 1945, Roosevelt visited New York City cardiologist Dr. Howard Bruenn after complaining of a headache.

Roosevelt's blood pressure reached 300/190 and he lost consciousness.
Bruenn diagnosed the event as a stroke and declared the president dead at age 63.
5. Dwight D. Eisenhower (34th president, 1953-1960)
Dwight Eisenhower began his first term in 1953 suffering from two serious illnesses, according to the NIH.
He suffered a heart attack in September 1955, which kept him out of the White House to recuperate until December.

Although Eisenhower obtained clearance from his doctors, the NIH reported that his cardiologists recommended against running for a second term.
The president decided to run for re-election anyway, which was followed by his second major health scare in June 1956, which resulted in a diagnosis of Crohn's disease.
Eisenhower underwent exploratory laparotomy and ileal bypass surgery for a bowel obstruction, which were successful.
After a full recovery, Eisenhower was re-elected for a second term, despite opposition questions about his suitability for the office.

The following year, in November 1957, Eisenhower suffered a stroke, but eventually served out his presidency.
After leaving office, Eisenhower suffered multiple heart attacks in the 1960s.
He died of congestive heart failure on March 28, 1969, at the age of 78.
