Then I would generally recommend either doing Access to HE with at least life science 12 credits in biology and 12 in chemistry, otherwise do biology A Level to supplement your application.
Physiotherapy, dietics/nutrition, dental hygiene, and speech therapy are all regulated professions, and the qualifications/degrees you would need would need to be approved by their respective professional bodies. See the following links as reference:

A large number of dietics/nutrition degrees won't require specific A Levels; they just won't be from top end unis.
Speech therapy won't require specific A Level subjects, except for one uni where they ask for one science
Dental hygiene degrees/qualifications would require at least one science, with Biology being a requirement for a number of unis
Physiotherapy generally require A Level Biology/PE
It would be significantly easier if you did A Level Biology or Access to HE in a life science subject during a gap year before applying as this would allow you significantly more options. If not, then I can only see you doing nutrition/dietics or speech therapy.
Should you wish, you can alternatively do an accredited degree where there is a foundation year available e.g. for physiotherapy vai Wolverhampton. However, doing a foundation degree at one uni can somewhat limit you to doing the bachelor's at that uni only i.e. not flexible; transferring to different unis is usually not an easy process. So, if you decide to do a foundation year for a specific degree, then make sure you want to do the degree at that uni only.
Do also note, a number of accredited degrees for the roles above generally don't require you to attned a top end uni, so you're fine to go to a less competitive uni should you desire.
Let me know if you want pointers on doing Access courses or A Level Biology privately.
