A sensation that food or liquids are becoming difficult to swallow can have several causes, including reflux, inflammation, neurological conditions, and structural problems.
Persistent or progressive difficulty swallowing should be assessed, especially if it occurs alongside unexplained weight loss, persistent heartburn, vomiting, or chest discomfort.
11. Persistent Indigestion or Abdominal Discomfort
Occasional indigestion is extremely common. But persistent indigestion, bloating, abdominal pain, early fullness, nausea, or unexplained appetite changes deserve attention when they continue or worsen.
These symptoms can arise from relatively common digestive disorders, but persistent symptoms should not be self-diagnosed.
12. Changes in the Breast or Chest
For both women and men, changes in breast tissue can include:
- A new lump
- Persistent swelling
- Skin dimpling
- Changes around the nipple
- Nipple discharge, particularly bloody discharge
- A change in breast size or shape
Many breast changes are not cancer. Still, a new or unusual change should be examined rather than ignored.
13. Persistent Fever or Night Sweats
Repeated unexplained fever or drenching night sweats can occur with infections and inflammatory conditions, among other causes.
Some cancers can also produce these symptoms. The significance depends heavily on the duration, severity, age of the person, and accompanying symptoms.
