The exiled Buddhist leader visited doctors in the United States who "advised His Holiness to rest for the next several weeks," a statement from his office said yesterday.
"As a result, His Holiness' planned October US visit has been cancelled," the statement said, apologising to all involved in organising the trip.
The Dalai Lama had scheduled several stops, including Philadelphia, where he was to receive the Liberty Medal in recognition of his advocacy of human rights.
The Nobel laureate has appeared to be in good health in recent years, although in 2002 he was hospitalised in Mumbai for an infection.
The Dalai Lama fled Tibet for exile in India in 1959 amid an abortive uprising against China's iron-fisted rule.
His spiritual teachings have won him a global following but he remains shunned by China, which has tried to ostracise leaders and artists who deal with the monk.
The Dalai Lama, an avowed pacifist, says that he recognises China's rule over Tibet and is seeking greater freedoms.
China insists that the Dalai Lama is nonetheless a "splittist," and some younger Tibetan activists in exile have advocated a more militant approach.
As his age advances, the Dalai Lama has given up his political role and instead delegated to an elected government in Dharamshala, India, voted by exiled Tibetans.
The Dalai Lama has also increasingly spoken of succession and has not ruled out picking his reincarnation before his death, fearing that China would instead pick its own boy whom it would use to advance its agenda.
