Praise be to Allaah.
Fasting is obligatory for
every adult Muslim who is able to fast. If a Muslim is unable to fast
because of a sickness and he will be harmed or the sickness will be made
worse by fasting, or if he needs medical treatment during the day in
Ramadaan such as pills and medicines and other things that are eaten and
drunk, then in his case it is prescribed not to fast, because Allaah says
(interpretation of the meaning):
“and whoever is ill or
on a journey, the same number [of days which one did not observe Sawm
(fasts) must be made up] from other days. Allaah intends for you ease, and
He does not want to make things difficult for you”
[al-Baqarah 2:185]
And the Prophet (peace
and blessings of Allaah be upon him) said: ‘Allaah likes you to avail
yourselves of His concessions as He hates you to disobey Him.” Narrated by
Imam Ahmad (5839) and classed as saheeh by al-Albaani in Irwa’ al-Ghaleel
(564).

Based on this, if it is
proven that fasting will harm you, based on the testimony of a trustworthy
doctor, then you must not fast and it is not permissible for you to fast,
because Allaah says (interpretation of the meaning):
“and do not throw
yourselves into destruction”
[al-Baqarah 2:195]
And the Prophet (peace
and blessings of Allaah be upon him) said: “There should be neither harming
nor reciprocating harm.” Narrated by Ibn Majaah (2341) and classed as saheeh
by al-Albaani in Saheeh Sunan Ibn Majaah.
Because you fasted last
Ramadaan and were not harmed by it, what we think is that that you should
consult another doctor who is more trustworthy and more knowledgeable than
the first about your condition. If he tells you to fast then fast, and if he
tells you not to fast then do not fast.
With regard to making up
missed fasts, if your sickness is temporary then you have to wait until
Allaah heals you, in sha Allaah, then make up the days that you did not
fast, because Allaah says (interpretation of the meaning):
“but if any of you is
ill or on a journey, the same number (should be made up) from other days”
[al-Baqarah 2:184]
But if your sickness is
ongoing and there is no hope of recovery, then you have to feed one poor
person for each day.

to feed the poor, please see the answer to question no.

We ask Allaah to decree
healing and well being for you and for all the sick Muslims.
And Allaah knows best.
