What causes bloating after eating only a slightly larger amount of food?

Dizziness after prolonged低头 (bending the head down) is generally caused by non-pathological and pathological factors, such as cervical spondylosis or benign paroxysmal positional vertigo (BPPV). The specific analysis is as follows:

1. Non-pathological causes

Incorrect sleeping posture often affects cerebral blood supply, leading to dizziness after keeping the head lowered for a long time. Usually, no special treatment is required; improving sleeping posture can effectively relieve symptoms.

2. Pathological causes

1) Cervical spondylosis

Prolonged periods of working with the head bent forward or trauma may commonly lead to cervical spondylosis, causing dizziness. This is usually due to cervical osteophyte formation compressing blood vessels. Treatment under medical guidance may include oral medications such as ibuprofen sustained-release capsules or celecoxib tablets.

3) Benign paroxysmal positional vertigo (BPPV)

BPPV is typically caused by dislodged otoliths (ear stones), which often results in impaired balance. Dizziness may occur after prolonged bending of the head. Under medical guidance, medications such as flunarizine hydrochloride capsules and mecobalamin tablets may be prescribed.

In addition, brain disorders may also commonly cause dizziness after prolonged低头. It is important to seek timely medical evaluation at a hospital and receive appropriate treatment based on the severity of the condition.
